Deletion of Matrix Column Using " linalg::delCol " Command

I am trying to delete the second column in the below matrix using the command:

linalg::delCol(network_station_coordinates_dbl,2 )

1  NaN  5125.06200000000  1201.78500000000
2  NaN  5310  1430
3  NaN  5700  1190
4  NaN  5280  1030

but I receive the following error:

   _Cell contents reference from a non-cell array object._

_Error in cell2mat (line 43)
cellclass = class(c{1});_

_Error in Program_2014 (line 131)
network_station_coordinates_dbl =
cell2mat(network_station_coordinates_cel)_

Can someone please explain to me why this is and what I require to solve this issue?

network_station_coordinates_cel is not a cell array but you're passing it to cell2mat. Do

whos network_station_coordinates_cel

and see what it says.

Also, I don't believe :: (double colon) is a valid MATLAB operator, at least not that I've ever seen.

Justin's "Answer" moved here since it's not an answer to the original question but a reply to me:

Hi Image,

I searched the internet for a way of deleting columns and rows of a matrix and found the linalg::delCol command.

I then looked at how to use it in MatLabs Help file.

It states it is a valid command but will not process when I try to use it (returns an error).

If "network_station_coordinates_dbl" is the name of your variable and you want to delete the second column, do this:

network_station_coordinates_dbl(:,2) = [];
