Hi Silbelo,

Is there some specific type of functionality you are trying to achieve? If not, then the same format as in many other programming languages should suffice:

output1 = func1(input1);
output2 = func2(output1);

Hi Dustin, i'm trying to maximise a likelihood function which involves some double integral over a product of two functions where one function's parameters are known and the other one is a log function times an integral, i have a code where i'am doing the integration of one function first and the result i need to mutiply with the second function and take the final integral of.i have at the moment used function handles which seems to work except the results are not good:

output1=function1(input1)

output2=function(input2)

output1=@function1

return;

Thanks

Can you post a simple example here to clearly demonstrate the problem? Otherwise, in your case, I don't see why output2 = function(function1(input1)) would not work.

If I understand the question correctly:

function [A] = func1(B)
A = sin(B);
function [C] = func2(D)
C = func1(B);

Does this help to understand how arguments are forwarded??
