basically i have 3 different columns: a, b, and c, which are all doubles

a = [1;2;3]; b = [2;0;1]; c = [1;0;1];

and i want to combine them into one, say d..

d = [121; 200; 311];

so d is a 3x1 vector od doubles

I'm pretty sure there's a better way but this will work:

    cellfun(@(x)str2double(x(~isspace(x))),cellfun(@(x)num2str(x),mat2cell([a b c],ones(size(a,1),1),3),'uni',false))

%Needs more work to accept decimals.

no decimals needed in my case, only ever going to be integers

An alternative:

str2num(sprintf('%i%i%i %i%i%i %i%i%i',a,b,c))
