Sir plz help me to rectify this error

X=reshape(x,size(Y));

where x=1; and Y=256 * 256 uint8

I got the error like this

"To RESHAPE the number of elements must not change."

Since x=1, you can use ones():

X = ones(size(Y)); % X is a double

If x is not one, but some other scalar, then you can use.

X = x * ones(size(Y)); % X is a double

If you want X to also be uint8, pass that class in:

X = ones(size(Y), 'uint8'); % Now X will also be uint8

Thanks a lot sir

You cannot reshape a scalar into a 256 by 256 matrix. reshape() cannot create new data.

Perhaps you want

X = repmat(x, size(Y));
