What is wrong with my code?

Hi everyone I don't know how to fix this code. I don't what's wrong

Function below this sentence.

function [y] = fcn1(x)

total = 0;

term = zeros(1, 100);

for k = 1:100

term(k) = pi/(12+ k^b);

total = total + term(k);

if (term(k) < loop_limit)

break

end

end

end

Function Call below this sentence

clc; close all; clear all

b = 3;

loop_limit = 0.001

y =fcn1(3)

Error message below this sentence.

Unrecognized function or variable 'b'.

Error in fcn1 (line 5)

term(k) = pi/(12+ k^b);

Error in fcn1call (line 4)

y =fcn1(3)

Any input would be greatly appreciated

In the line inside the function:

term(k) = pi/(12+ k^b);

but you didn't send b as an input parameter nor did you define it inside the function.

The same is for variable loop_limit. They exist in totaly different memory space comparing to the function.

Thank you, I got it fixed.
