Hi everybody,
I've created a matrix with all the significant values from performing ttest (19x19 with 1's and 0's) and I would like to extract the coordinates (like (3,2)) for all the 1 values. And then put them into a matrix like [3,2; 4,2; ...].
Is this possible? And does anyone know how?
Best regards,
Christian

[ii,jj]=find(a)
