I want to convert 2D data to 3D.
Currently I use :
ij=0;
for ix=1:200:size(data1,1)
ij=ij+1;
data(ij,:,:)=data1(ix:ix+199,:);
end
However it is very slow. I try the following code then:
permute(reshape(data1, 200, 8578, 200), [1 3 2]);
But, I get the following error:
Error using reshape
To RESHAPE the number of elements must not change.
Size of data1 is 1751600x200.
Thank you for help.

xxx78*2 is going to end in 56 not in 16. The size should be 8758 not 8578

yes, you are correct, the size should be 8758 not 8578
