Why is my function not working?

I am very new to MATLAB, as in, started two days ago because I'm trying to translate some code from mathematica.
For context x0 = 1 and x,x2 are undefined in this function
function [f355] = f355(x,x0,x2)
%UNTITLED4 Summary of this function goes here
% Detailed explanation goes here
if x >= 0
f355 = (Omega00)*sqrt((1)+((Lambda355*x)/(pi*(Omega00))^2));
elseif (x<=(x2+x1+x0))&&(x>=x0)
f355 = NewBWaist(Omega00,x0,f,Lambda355)*sqrt((1)+(Lambda355*(x-x0-x1)/(pi(Omega01)^2)));
else x >= (x0+x1+x2)
f355 = NewBWaist(NewBWaist(Omega00,x0,f1U,Lambda355),x2,f2U,Lambda355)*sqrt((Lambda355(x-sumxU))/(pi*(Omega02)^2));
end
When I run "f355(10,1,20)" I get an error
"Index in position 1 exceeds array bounds. Index must not exceed 1.
Error in m118codeInprogress (line 111)
f355(10,1,20)"
Any advice would be most welcome. Thanks.

Apologies,
Omega00= 3.5
Lambda355= 0.000355
The rest of the variables are themselves defined by other functions with yet more variables. The other functions are all working though.

Rename your output variable name and run your code. As other functions are working properly, your code should work after the correction as well.

Avoid using the name of the function as name of the output. This is confusing only.
Which is the failing line? In this line f355 is used as a variable, not as a function.
See this example:
sin(0.1) % Fine
sin = 15; % Now sin is a variable
sin(0.1) % Error: 0.1 is no valid index

Right I see, I ran a calculation earlier (since deleted) with f355= so I guess it's now assigned as a variable?
Thanks for the advice.
