Need help creating a function with multiple inputs.

Here is my function.

function N = line(A_0,a,t)
N = exp.^(A_0./a).*(1-exp.^(-a.*t));
end

It's giving me an error saying that function name 'line' is known to Matlab by its file name 'N'. How can I fix this?

You need to save it to the file line.m instead of saving it to N.m

Caution: line() is the MATLAB function used to draw lines. It is not recommended that you use it for your own function name!

I changed it to this:

function N = lin(A_0,a,t) N = exp.^(A_0./a).*(1-exp.^(-a.*t)); end

but when I try to put in values for lin(A_0,a,t) it says "Error in lin (line 2) N = exp.^(A_0./a).*(1-exp.^(-a.*t));"

How do I fix this?
