how can i write a code

hi,

how can i write code that do this algorithm:

Repeat for α = 0 to 180

Repeat for u = 0 to 255

Repeat for v = 0 to 255

{

ρ= u cos α + v sin α

g(ρ, α) = g(ρ, α) + g(ρ, α) δ(u cos α + v sin α -ρ) }

it's with for loop

It's not MATLAB ?

no, i need to convert this but i dont know how to write g(ρ, α) in MATLAB

You can try this

for alpha=0:180
    for u=0:255
        for v=0:255
            rho = u*cos(alpha) + v*sin(alpha)
            % your code 
        end
    end
end

Create required functions outside the loops or as a separate file and call them where required.

the function is my probalm, the else in know how to do

Check documentation for creating function. Can you elaborate your problem?

It has to do with image processing, switching over the Fourier transform spectrum log and getting an angle by radon transformation
