Hi guys,

I am trying to numerically integrate a function and keep receiving the error "Not enough input arguments."

My code:

integral(fun,0,1)

while fun.m reads:

function [ y ] = fun( x ) y = x*2 + 1; end

What am I missing here? Thanks in advance!

You need to use a function handle... try

integral(@fun,0,1)

thank you, it works now

I have another question: I run a script which defines a bunch of variables which are visible in the base workspace (right?). Then, the script runs the function which is supposed to use these variables. is there a quick way to make a function "see" the variables from my base workspace or do I have to define all variables as global in both the function and the script?

cheers

Yeah... pass those variables as input to the function (best practice).

Also, please accept answers that you find helpful. (My first one.)
