How can I generate a code for this equation?

compute this formula

Answer 1

[Manvi Goel]

You can use the following code for this

a = [429.494, 93.112, -6.050];
N = 1024;
temp = 0;
lambda = zeros(1, N)
for i = 1:N
    for j = 1:3;
        temp = temp + (a(j) * (((i - 1) / N - 1) ^ (j - 1)));
    end
    lambda(i) = temp;
    temp = 0;
end

The lambda array will contain the final values.

If you have Symbolic math toolbox then this can be done in an elegant way. In case you don't have symbolic math toolbox (like me) this code will do:

N=1024;
a=[429.494;93.112;-6.050];
wavelength=zeros(N,1);
for m=1:N
    temp=zeros(3,1);
    for n=1:3
        temp(n,1)=a(n,1)*(((m-1)/(N-1))^(n-1));
    end
    wavelength(m,1)=sum(temp);
end

with so many thanks because of your help but I got this error' Dimensions of arrays being concatenated are not consistent.'

[Raj]

At which line are you getting this error? I ran the code and I am not getting any error.

[madhan ravi]

It’s a homework obviously.

[FSh]

Dimensions of arrays being concatenated are not consistent.

This is the error. not homework, that is a part of my data analysis.
