Use matlab's surf to draw a three-dimensional surface map

Task requirements:

• In a recent experiment, I encountered a parameter discussion problem. There are two independent variables and one dependent variable. The two independent variables may affect each other. It is necessary to discuss the parameters through experiments to find the value of the two independent variables when the dependent variable is the maximum. .
• When drawing an image, it is natural to think that a three-dimensional image can be drawn, where the x-axis and y-axis represent two independent variables, and the z-axis represents the dependent variable
