Extract coordinates from a significance matrix

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

a=randi([0 1],19) % Example
[ii,jj]=find(a)
out=[ii jj]
