But you do, have a value for certain combination of these coordinates, like D(1,4,3). There is a 2:1 homomorphism from the unit quaternions to SO (3) (the rotation group). https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one, https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one#comment_355882, https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one#comment_355883, https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one#comment_355885, https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one#comment_355923, https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one#answer_216429, https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one#comment_355928, https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one#comment_355950, https://www.mathworks.com/matlabcentral/answers/277124-how-to-merge-three-matrix-into-one#comment_355952. But one of the things that I really like about MATLAB is their documentation. Agree, desciption is confusing. ); This creates 'D' as part of the variable loading loop, so you have it when you have loaded all your variables. Find elements in table without looping (Matlab). Other MathWorks country The A matrix contains X coordinates. Instead of inventing new classes of variables, it is much better to use the possibilities, which are offered by the programming language already. How would I do that at matlab ? offers.

Then i use below code to convert a1, a2 and a3 to b1, b2 and b3 (x1 column matrices). Learn more about cell, cell array, cell arrays, merge, matrix, matrices MATLAB I have 8 points (1 at each corner). So for example it will be: So what we have at the moment is a cube whose bottom left corner is at (1, 1) meters, and top right corner at (1.5, 1.5) meters. Hi all, I've got 3 matrices [nx3], made up from xyz files, and I need to combine them into: x=[a(:,1),b(:,1),c(:,1)]; y=[a(:,2),b(:,2),c(:,2)]; z=[a(:,3),b(:,3),c(:,3 . And this Support section is also very nice. MathWorks is the leading developer of mathematical computing software for engineers and scientists. In your case [A,B] is the most natural. It was a mistake on my part, the matrix must have the dimensions 26x300. In your for loop, the easiest way might be something like this: for k1 = 1: . However, here is one of many possibilities, L1= [a,c;b,c]; L2= [d,d;d,d]; result=cat (3,L1,L2); Sign in to answer this question. Matrices a1, a2 and a3 (x5).

Instead of explicitely store the data in a huge 4D matrix, you could write an anonymous function. yes its a matrix but i put a spaces between three matrix to explain to you how i want to merge these matrices, From what you posted, in D, the frist three rows contain 6 elements, and the other rows contain 9 elements. Or, as a one-liner, using left-hand indexing: A = cumsum(ones(5,4),2), B = 10 * A, C = 10 * B, % left-hand indexing trick (NewMatrix should not exist), NewMatrix(:, (1:3) + (1:3:3*size(A,2)).' Your question is a little confusing. You can skip that part since your data are already in text files. D = reshape([rfun(A);rfun(B);rfun(C)],[],size(A,2)), The second method looks shorter but it actually requires some memory movement, so less efficient, D = reshape(permute(cat(3,A,B,C),[3 1 2]),[],size(A,2)). Hi, you can make column vector from a matrix by using linear indexing columnVector = Array(:); And if by "save all" you mean to concatenate these vectors, then its possible simply by using brackets: Could you delete my question please for once. I think I have to go the 4D route since I have to check at every time step if the Z coordinate of every point is below a threshold, so having all the Z coordinates stored at one place will help me a lot in that rather than having to call the function (I think). You can obtain this using. . Other MathWorks country % make sure this doesn't overwrite any files!

It's really awesome to have wonderful support in this community to help me kick start at this software. 1 Answer Sorted by: 7 Hint: order matters in matrix multiplication, and particularly, consider the order in which the transformations are applied. So far you have just coordinates for X, Y, Z, presumably generated with meshgrid. In MATLAB you have three options namely [A, B], cat (2,A,B) and horzcat (A,B). What is the size of the Matrix D, if it is a matrix! The C matrix will define the coordinates in the Z dimension: So for example if I want to access the coordinates of the bottom left corner of the "first face", I want to just type in: ans = [1, 1, 1] meters (unit is just to clarify). MATLAB allows two types of concatenations Horizontal concatenation Vertical concatenation When you concatenate two matrices by separating those using commas, they are just appended horizontally. Also, two matrices are combined into 'b' matrix as shown above; one of hem 33 eye matrix and one of them 13 ones matrix. They are coordinates (X, Y, Z) of points that represent a cube. ind = find (X target) ind = 1 3 14 20. You can compare the text files I generate in my answer to your text files to make sure they look them same. The comments will be helpful. For example, if you would like to raise a .

Edited: Azzi Abdelmalek on 4 Apr 2016 From what you posted, in D, the frist three rows contain 6 elements, and the other rows contain 9 elements. Sorry my English is not that good. It's overwriting the output because you're overwriting the output.Since I don't know what your code looks like, it's hard to know exactly why. Note that D has 2*n^3 elements, if n is the number of different elements in A,B, and C. That seems to be an inefficient way to organize your data; the same information is already in your n values. Thanks for replying.

For Matlab find the index "Find" statement is used. As you can see, they combined on a columnar basis, because there is a semicolon between combined matrices at 'b'. Alternatively, if you concatenate two matrices by separating those using semicolons, they are appended vertically. I have four matrices say A, B, C and D, all square matrices. how to combine two matrices?. your location, we recommend that you select: . You have to precise if you want to append with zeros or nans. My question is : How can i do this with a loop? I will give it a try. strjoin. String Array in Matlab, an array is used to store the elements that are of the same data type.

I am sorry but my partner doesnt allow me to ask question about our data and code. The result will have 8 times as many entries, but you only have 4 matrices to draw data from, so it is not clear where all the additional entries will come from. A is 420x420x3 and B is 420x420x3.
