# Help with logical operations

Posts: 2Member

Hello everyone !
First of all i want to say im new to Matlab ( also my english sux ) .

I have 3 arrays -

z=[z(1) .... z(35)]
y=[y(1) .... y(35)]
D=9.38 for example ; D is calculated early

i need to calculate y for each ZD .

Condition
[b]Z<=D
value true - correspond y ; Z<=D
value false - correspond y=0 ; Z>D[/b]

There are values for Z and Y
Z=[0.00 0.05 0.10 0.25 0.50 0.75 1.00 1.25 1.50 1.75 2.00 2.50 3.00 3.50 4.00 4.50 5.00 5.50 6.00 6.50 7.00 7.50 8.00 8.50 9.00 9.50 10.00 10.50 11.00 11.50 12.00 12.50 13.00 13.50 14.00];
total 35 values

Y=[0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.848 2.277 3.483 4.449 5.241 5.909 6.487 6.998 7.454 7.864 8.232 8.559 8.847 9.095 9.306 0.000];
total 35 values
