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.

what is the size of the variable called: data1?

It looks like you have a sizing problem while converting your 2D variable into 3D one.

Size of data1 is 1751600x200

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
