This is my first time using Matlab , I tried to write a function that gives you CSR (Compressed Sparse Row) the result are not correct. The pair of square brackets [ ] used in the declaration of the array is itself a concatenation operator. Any particular element can be accessed using indexing in MATLAB. So, if we are taking matrix A, then for the inverse matrix , we can say: A.AT= I In this way, if we have the value of A and want to know the inverse of it, we use the following equation: AT= I/A. The C1 lines have a distinct contrast between the C2 lines and the M2 lines, and between the C3 lines and the C3 image, says Ian Hetherington, a lecturer in image theory at the University of Oxford.
