Use the same equation and pass the different parameters as extra parameters in a loop. See the documentation secton on Passing Extra Parameters to understand how to do this. Then use one or more loops to select the parameters at each iteration. How you choose to plot them — in a single axis using hold or as subplots (or using the stackedplot function) — is your choice.
A very efficient way to do this is to use the ndgrid or meshgrid function to create matrices of the parameters, then reshape them to column vectors (using reshape or the (:) subscript convention). That way, you can use one loop to use all combinations of your parameters.
