How can I do a graphic using plot and changing the values of x axis from 1 to 500 at intervals of one?

Hello, I'm trying to calculate the wavelength, for this I have previously created that function in matlab, and now I have to calculate the wavelength with a loop, which changes the value of the x-axis from 1 to 500 at intervals of one. And make a graph with the plot function. I have tried, but I always get the message "...exceed arrays bounds". I've tried to fix it, but I'm learning Matlab and I need a little bit of help.

That's what I've done:

First, the name of the function I've created: function [longitudonda] = longitudonda(T,H)

And here, you can see the codes where I'm having problems:

H=1:500; 
T=10; (this is the period)
for K=1:length(H)
    longitudonda(K)=longitudonda(H(K),T);
end
plot(H,longitudonda)

Greetings.

for K=1:length(H)
    longitudonda(K)=longitudonda(H(K),T);
end

When K is 1, the right hand side is longitudonda(H(1),10) which calls the two-parameter function longitudonda .

After the function has been called and has successfully returned, the result (hopefully a scalar) is assigned to the scalar output location longitudonda(K) -- a variable named longitudonda

When K is 2, the right hand side is longitudonda(H(2),10) . But now longitudonda is a variable not a function and it does not have as many elements as required to index it at H(2),10 .

The problem arises from using the same output variable name as the name of the function.

Hello, I've fixed the problem!!!

Thank you.
