creating a matrix from 2 vectors and a function loop

Im looking at how the power generated varies with the radius of the turbine wheel and the radius of the outlet water nozzle. Iv had to create these two vectors for inputs.

wheel_radius = [0.12:0.02:0.3]
nozzle_radius = [0.002:0.001:0.01]

I am told using loops pass each combination of wheel_radius and nozzle_radius to the waterwheel_generate function which i am given and also create a matrix gen_power that contains the power generated for each combination, the nozzle_radius should change with each column and the wheel_radius with each row.

The function waterwheel_generate.p has the Format: power_output = waterwheel_generate(wheel_radius, nozzle_radius)

Calculates the generated power for a turbine wheel connected to a generator based on a particular turbine wheel radius and water outlet nozzle radius. The inputs are in metres and output in watts.

[wheel_radius,nozzle_radius]=meshgrid(.12:.02:.3,.002:.001:.01);
for k=1:numel(wheel_radius)
    power_output(k)=waterwheel_generate(wheel_radius(k),nozzle_radius(k));
end
power_output=reshape(power_output,size(wheel_radius));
