Remove single cell from matrix

7 views (last 30 days)
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
