MATLAB: How to make a column of elements in a cell array be empty cell elements?

Question

Suppose I have a 4×4 cell array,

 x = num2cell(rand(4));

And i would like to make the first column of elements be empty cells. How do I do that?? I do not want to delete the column, I just want each element in that column to be empty. I tried using the following:

 x{:,4} = [];

but i get this error. The right hand side of this assignment has too few values to satisfy the left hand side.

Answer 1

x = [cell(4,1) num2cell(rand(4))]

Or maybe you want

x=num2cell(rand(4))
x(:,1)={[]}
