In order to draw a 3D graph under inequality constraints, it is necessary to specify the drawn functions and constraints first. According to offer you the function and the constraint condition, we can get: the function of T = 1 /((1 + a + 0.25 c(0.75) ^(2)) ^(1/3)), and 0 & lt; a< 1,100 -(0.75a+0.25c)> 0.
Next, we can use the meshgrid function in matlab to set a certain range for the variables A and c and calculate the function values under the inequality constraints. The meshgrid function generates a two-dimensional plane from the set range of A and c to store the values of the function T.
The specific code is as follows:
clear;clc; [a,c] = meshgrid(0:0.1:1); % 两个变量的范围从0到1，步长为0.1 T=(1+(0.75*a+0.25*c).^(-2)).^(-1/3); % 计算不等式约束下的函数值 T(100-(0.75*a+0.25*c)<=0) = NaN; % 把不满足不等式约束的函数值赋值为NaN mesh(a,c,T); % 绘制三维图
After the above code is executed, the 3D graph under the inequality constraint can be obtained.
