Deleting a Column from an array?

I am given a 21 x 345 array. I need to delete JUST column 190. How would I do so and keep all the rest the same so that it is a 21 x 344 array

If ‘M’ is your matrix, just set the entire column to the empty array []:

M(:,190) = [];

you can use the indexing of arrays to delete a column.

A = 1:10;  %1x10; counting from 1 to 10;

to delete column 9 (ie number 9)

 A(:,9)=[] % which reads all rows of A in column 9 is now empty.

Thats what the : in the first part as indexing goes (rows, columns)
