Hello,
I have the following function:
function [A,N] = area(f,a,b,varargin)
%Structure definition
s = struct('fh',f,...
'a',a,...
'b',b,...
'N',64,...
'Tolerance',10^(-6),...
'Algorithm','MiddleSum');
... rest of the code
The structure contains the defaults values that will be used to run the function if the user doesn't provide values for 'N',Tolerance and Algorithm.
I need to use a SWITCH statement to overwrite the structure values if the user does provide any or all of the values, and it must be case insensitive.
So if the user enters area(X^2,0,2,'N',2,'AlGoRithm','TrapeZoid') the structure should replace the default values N=64, algorithm = MiddleSum, with N=2 and Algorithm = Trapezoid.
Can someone please help me?

You can copy the code I used in my FEX submissions (see WBM, readfile, BlandAltmanPlot or RegGrow).
If you simply want to overwrite the default values you don't need a switch, you can simply use a loop.

Hi, yes I looked at them. I'm pretty new with Matlab so it's hard for me to understand what's going on there :/ Do you have a simpler code that could help me a little bit?

Do you have trouble finding which function you need to look at? Did you run any example with the debugger (so you can step through the code line by line)?
