Having issues with a function: creates NxN matrix instead of a column vector

Question

Hello all,

Below is the function that I've created:

function p=logodds(p,sigma,N)
e = normrnd(0,sigma,[N,1]);
Lo = log10(p/(1-p)+ e);
p = 10.^Lo/(1+10.^Lo);
end

When I call the function, it gives me NxN matrix in which 1 column vector of a result of the function and the others are zeros.

I need just a column vector of a result.

Thanks in advance

Are the inputs p, sigma, N scalar values or vectors? Does normrnd return a vector or a scalar? That seems to be a function you wrote

Dear Jeremy,

The inputs p,sigma and N are scalar values, whereas normrnd return a vector.
