Hi,

I have a matrix with x position as rows, y position as columns and magnitude as data at (x,y). How can I convert this to a 3 column matrix with (x,y, magnitude)

Thanks

magmatf.mat

Sorry,

I should rephrase my question. I have a matrix (magmatf- attached)- lets call the rows as R1 and columns and C1 . I created this using sub2ind and accumarray. Now I want to convert this back to a 3 column matrix with first two columns being the combinations of the (R1,C1)indices and the third column should be the value at R1(ind),C1(ind)

Thanks
