Replacing non-integer values

I have an array of all numeric values but it is a mix of integers and non-integers. How could I replace an non-integer with 0, for example? Also, the array is fairly large (about 130k rows).

Thanks in advance!

a(ceil(a)~=a)=0

If 'a' is your array then use the following:

a(arrayfun(@(x) ~isinteger(x), a)) = 0;

"isinteger", there's what I was looking for. Thanks so much.

iit works for integer type values only. if you have data in default MATLAB format(double type) then you should use the following:

a(arrayfun(@(x) mod(x, 1) ~= 0, a)) = 0

Because in case of default MATLAB format data it will make all the values 0 because they are not integer

The code you posted replaces the entire array with zeros for some reason. I just wanted the numbers that have a decimal place to be replaced with zero. Does matlab classify an non-integer as a non-number or something? ie. 0.5 and 3 are both integers?

use this:

a(arrayfun(@(x) mod(x, 1) ~= 0, a)) = 0

I explained the reason above

Why arrayfun?

it could be done both ways but I am learning about arrayfun and cellfun as well so I used it. Since both solutions work well so I posted this one

Thanks, it works great!
