How to get output using a function with two parameters of different range

For instance, I have a function x = cb( a, b)

the paramter a ranges from 0 to 1 and b ranges from (2 to 20).

How do I perform a for loop to plot x for these parameters range.

Your help will be greatly appreciated

Best wishes

This will be a 3D plot, because you have two indices for the input and 1 value for the output. There are many different types of 3D plots. So how do you want the output to look like?

Yes thanks for responding. I will like a 3D line plot.

The ranges a and b will be on the y and x axis respectively, while the out put (x) will be on the z axis

Do you want to display the surface as points, surf, patch, bars, the z value encoded as color?

[Tino]

Yes thanks for responding, I will like to display the surface as points and the z value encoded as color.

Also I would like to display in the plot the optimal values for x function and the value of a and b that gives the optimal x values if possible

Hi,

As per my understanding, you want to display a surface plot between a, b, and x. You can do the same as follows: -

a = linspace(0, 1, 10);
b = linspace(2, 20, 10);

[X,Y] = meshgrid(a,b);
Z = cb(X, Y);

surf(X,Y,Z);

For more information, check out the documentation link below: -

meshgrid() linspace() surf()
