How to delete only a range of cells in a column in matlab

Question

I have a 23x5 cell array, and I'm trying to replace all cells but the first with an empty cell in one column.

When I try array{2:end,4}=[] I get "The right hand side of this assignment has too few values to satisfy the left hand side."

Still being confused with how Matlab handles different classes, I also tried array(2:end,4)=[] and get "A null assignment can have only one non-colon index."

I know a for loop could easily empty the contents of each cell, but I feel like there must be an easier solution to fix this.

Thanks for the help.

Try using:

array(2:end,4) = {[]}

For example:

>> array = cell(23,5);
>> array(:) = {1};
>> array(2:end,4) = {[]}
array =
