send variable to workspace

i have a code starting with a function, the only variable i get in the workspace is 'ans'. i have other variables inside my code and want to send them to workspace. how can i send variables from the function code to the work space?

Please set multi variables to the outputs of your function, for example,

function [a, b] = sum_test(a1, a2)
a = a1 + a2;
b = a1 - a2;

a and b is output variables of the function.

And call this function from command window,

 [a, b] = sum_test(1, 2)

a =

     3

b =

    -1

Two output variables will return.

ihab - if there are variables in your function that you wish to return with your function, then update the output parameter list with these variables (see Declare function name, inputs, and outputs. For example, if you have three variables in your function body, say x, y, and z that you wish to return then your function signature would looks something like

 function [x,y,z] = myFunction(a,b,c)

The body of myFunction would then initialize the output parameters and perhaps update them as the code executes. At the command line, you would call this function as

 >> [x,y,z] = myFunction(1,2,3)

so that the output is assigned to the three output parameters.
