MATLAB: How can i solve the error? >> f_function Error: File: f_function.m Line: 1 Column: 29 Unbalanced or unexpected parenthesis or bracket

Question

function y = f_function(rand(1,1)*depth,neighboure_Noise(p))
y=(1/rand(1,1)*depth*neighboure_Noise(p));
end

the error are like this

>> f_function
Error: File: f_function.m Line: 1 Column: 29
Unbalanced or unexpected parenthesis or bracket

Answer 1

The portion after the function name can only be parameter names, not expressions. You appear to be using parameters depth, neighboure_Noise, and p, so you would need something like

function y = f_function(depth, neighboure_Noise, p)
  y=(1/rand(1,1)*depth*neighboure_Noise(p));
end

You would not be able to run that by click the green arrow: you would have to go down to the command line and pass in appropriate parameters, such as

    Noise = sort(rand(1,50));
    noise_index = 17;
    depth = 14.38;
    result = f_function(depth, Noise, noise_index)
