Hello!

I was wonderif if it is possible to remove a single cell from a matrix without having to resize it or remove an entire row or column.

I am specifically trying to remove A(2,2) from a 3x3 matrix. I know this is possible in a cell array can the same be done with a normal matrix.

I was thinking the output of removing the cell would be NaN but I cannot seem to get it to work without getting an error.

>> b(2,2) = []

A null assignment can have only one non-colon index.

>> b{2,2} = []

Cell contents assignment to a non-cell array object.

> This was not a cell array format when I attempted this method.

”Remove single cell from matrix“

b(2, 2) = nan; % since matrix cannot have holes replace it with nans

Thank you for your time and help!!
