YOu need to proceed like this:

m = 300 ; n = 100 ; 
x = linspace(0,100,m) ; 
eta0 = 2 ; 
L = 100 ; 
W = 100 ; 
v = 0.14 ; 
t = 5.95 ; 
y1 = linspace(-150,-50,n) ; 
[X,Y1] = meshgrid(x,y1) ; 
T1 = eta0*v*t/(2*L)*(1-cos(pi/50*X)).*(1-cos(pi/100*(Y1+150))) ; 
y2 = linspace(-50,50,n) ; 
[X,Y2] = meshgrid(x,y2) ; 
T2 = eta0*v*t/L*(1-cos(pi/50*X)) ; 
y3 = linspace(50,150,n) ; 
[X,Y3] = meshgrid(x,y3) ; 
T3 = eta0*v*t/(2*L)*(1-cos(pi/50*X)).*(1+cos(pi/100*(Y3-150))) ; 
X = [X ; X; X] ; 
Y = [Y1 ; Y2 ;Y3] ; 
eta = [T1 ; T2 ; T3] ; 
surf(X,Y,eta) ;
