3D volume in a single variable of dimensions

Hello everyone!

I ran into an issue while trying to code data into a 3D volume in a single variable of dimensions. For example lets say I have data on Excel totaling 25 points spread in a 5x5 manner. How can assign x to it as a 3D volume? I understand it would be something like x(:,1,1)=[ the data copied from excel] however I have issue with the numbers in the parentheses with mismatch dimensions. Can anyone explain the correct way of doing this? Thank you!

how about

x(:,:,1) = [the data copied from excel]

Hard to say. If Y is the data copied from Excel, then maybe Dario wants

x(:,1,1) = Y(:);

Or maybe not. Maybe Dario wants

N3 = ceil(numels(Y) ^ (1/3));

x = zeros(N3,N3,N3);

x(1:numel(Y)) = Y(:);

Or something else.
