I have to write a matlab function, function [in,fr]=infr(x) that takes an array x of real numbers and returns arrays in and fr holding the integral and fractional parts respectively of all the numbers in array x but don't know where to start.

You don't know, where to start. The give us some tips: Do you have a computer already? With installed operating system? Did you install Matlab already? Do you know how to write a function and save it as M-file? Did you try anything to solve your homework by your own?

infr = @(x)[fix(x),rem(x,1)]
or:
function [in, fr] = infr(x)
in = fix(x);
fr = rem(x,1);
end

I'm not happy about this homework solution. It would be more helpful, for Karen and the forum, if she learns how to ask a good question.

Often, I think, when a student doesn't know where to begin they also don't know how to ask the right question.

+1 Geoff.
It could have been improved by "Any hints to get me started?", but she wasn't asking for a full solution
