MATLAB: Deleting a Column from an array

arraycolumndeleterow

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) = [];

rows = any(isnan(myMatrix),2);
myMatrix(rows,:) = [];

Just use some basic MATLAB logical indexing:

>> X = M(M(:,1)~=0,:)
X =
    1    1
    2    6
    3    5
    5   55
    6   56
    7   69
   11    2
