MATLAB: How I plot this

3d plots

Please help me to plot this equation
Thanks in advance
log((1+alpha1*x/(1+alpha2*y))) -gamma*log((1+beta1*x/(1+beta2*y)));
alpha1=0.1; alpha2=0.2; beta1=0.2; beta2=1; gamma=1.3;

Best Answer

Here is one way:
alpha1=0.1; alpha2=0.2; beta1=0.2; beta2=1; gamma=1.3;
x = 0 : 0.1 : 10;
y = 0 : 0.1 : 10;
[xx,yy] = meshgrid(x,y);
f = log((1+alpha1*xx./(1+alpha2*yy))) -gamma*log((1+beta1*xx./(1+beta2*yy)));
figure
surf(x,y,f)
