I am trying to write a sparse function code for any matrix size. For example if i have a matrix:
A = [ 0 0 0 5
0 2 0 0
1 3 0 0
0 0 4 0];
for i=1:a for j=1:b if A(i,j) ~=0
S --> is the storage matrix for all the non zero elements for A matrix. In addition to this information(Index,Row Number, Column Number, Value) how do I include two more columns in the matrix which shows the next element in row & the next element in column.
