I am working on the Design of Experiment techniques and solved a L-27 problem using minitab software. here, i am using four input process parameter:
A have levels- [0 5 10]
B have levels- [4 8 12]
C have levels- [30 40 50]
D have levels- [300 400 450]
On the basis of these all, I have generates a non-linear Quadratic equation :
Y = 402 - 5.54 A - 3.6 B - 6.01 C - 0.87 D + 0.561 A*A - 0.124 B*B + 0.0147 C*C + 0.00018 D*D - 0.092 A*B + 0.0568 A*C - 0.0060 A*D - 0.096 B*C + 0.0202 B*D + 0.01056 C*D
I am studying the 3D response surf plot using minitab.
But the 3D response surf plot in minitab is not interactive and not good in quality.
Can any one help me to plot the 3D response surf plot using MATLAB.
Like this plot:
Dear Prof. Kirchsteiger,
The function is obviously depending upon the 4 variables; Y = f (A, B, C, D) .
But, if i want to study the effect of A and B on Y, then how to plot 3D response plot considering Y is output parameter and A and B input.
thak you, that's work. for my sript i have not the same color, and the curve have only two grid.
When I use this instruction
n = 20;
a = linspace(0.08,0.25,n);
b = linspace(300,1400,n);
that's very very good
thank you and work perfectly.
