if i use division function to calculate training and test variable as follow
function [training,test]=division(a)
number_elements = round(0.9 * length(a));
number_elements2 = length(a) - number_elements;
row_selection = randperm(size(a,1));
training = a(row_selection(1:number_elements),:)
test = a(row_selection(number_elements + number_elements2),:)
end
how to use result of the variable 'training' in other function, i.e how to pass specific result between different function.

muhammad - which other function do you want to pass the training output to?

introduce a global variable and store the data into it now use that global variable in other function. syntax "global new" (without quotation marks) will introduce a variable named "new" so that you can use this in all functions.
"Ordinarily, each MATLAB function has its own local variables, which are separate from those of other functions, and from those of the base workspace. However, if several functions, and possibly the base workspace, all declare a particular name as global, they all share a single copy of that variable. Any assignment to that variable, in any function, is available to all the functions declaring it global." (source: MATLAB help)
