External function calling inside another function

Can an external function created be called inside another function.Please explain with an example. Thanks.

Answer 1

[ES]

Definitely yes, provided the path of the external function (m file/m script) exists in the matlab path.

.m

function script1(arg1, arg2, arg3)
....
....
x=script2(arg4,arg5);

script2.m

function y=script2(arg6, arg7, arg8)
y=arg6 + arg7...

Here is a simple example of calling one function within another function:

 % Function 1 calling function 2
    function output1 = fun1(input1, input2)
    value_fun2 = fun2(input1, input2);
    output1 = value_fun2 * input1 * input2;
    end

% Defining function 2    
    function output2 = fun2(in1, in2)
    output2 = in1 + in2;
    end

You can save both function in the same folder then it will work fine

What if fun2 has to accept morethan 2 input

[Steven Lord]

Then you define it to accept more than 2 inputs and you have fun1 call it with more than 2 inputs. Nothing about this technique limits it to only working with two inputs.

out1 = fun1(2, 3, 4) 

out1 = 852

% Function 1 calling function 2
function output1 = fun1(input1, input2, input3)
    value_fun2 = fun2(input1, input2, input3, 42);
    output1 = value_fun2 * input1 * input2;
    end

% Defining function 2    
function output2 = fun2(in1, in2, in3, in4)
    output2 = in1.^in3 + in2.*in4;
    end

Hi!

How can I write a cylinder volume as a external fuction, there radius r , height h are fuction arguments?

best wishes
