Apr 12, · 1 Comment. A = matrix with some zero entries. Indzero = find(A== 0); B=A; B(Indzero) = max(max(A))+1; Min(B,,1) B(Indzero) = min(min(A))-1; Max(B,,1) U can use this sort of logic maybe. u can also go at it by gpu processing or mexing for faster results (this is exactly the type of probelms where u get the best rests with gpus Nd mexing). Use nonzeros to return the nonzero elements in a sparse matrix. Create a by sparse matrix that contains a few nonzero elements. The typical display of sparse matrices shows a list of the nonzero values and their locations. MATLAB ® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left to right. For example, consider a 3-by-3 matrix. You can reference the A(2,2) element with A(5), and the A(2,3) element with A(8).
