Hi all, can anyone please help to create code for the condition bellow

x = 10:20:200

y = 0.1:0.08:1

[X,Y] = meshgrid(x,y)

I = eye(13,10)

Z = 8.1.*0.7.*X when, X <= 60

else

Z =8.1.*42.*I ,X>60

mesh(X,Y,Z)

figure;

surf(X,Y,Z)

I hope its helpful;

x = 10:20:200

y = 0.1:0.08:1

[X,Y] = meshgrid(x,y)

I = eye(13,10)

Z = [];

for i = 1:12

for j = 1:10

if X(i,j) <= 60

Z(i,j) = 8.1.*0.7.*X(i,j);

else

Z(i,j) =8.1.*42.*I(i,j);

end

end

end

mesh(X,Y,Z)

figure;

surf(X,Y,Z)

x = 10:20:200;
y = 0.1:0.08:1;
[X,Y] = meshgrid(x,y);
Z = zeros(size(X));
Z(X<=60) = 8.1.*0.7.*X(X<=60);
Z(X>60) = 8.1.*42;
mesh(X,Y,Z)

figure;
surf(X,Y,Z)

thank you so much, it is actually perfectly matched.
