I have 3 row vectors that are quite long, but for example they are:
D=[0 0 100 0 250 0 300]
H=[4 2 0 5 0 0 1]
T=[7 9 12 4 9 4 12]
I want to remove the values from H and T that correspond to zero in D, but I want to leave the zeros in H and T.
For example, the above vectors would become:
D=[100 250 300]
H=[0 0 1]
T=[12 9 12]
How to do? Thank you in advance.

Ran in:
D=[0 0 100 0 250 0 300];
H=[4 2 0 5 0 0 1];
T=[7 9 12 4 9 4 12];
D,H,T
D = 1×7
0 0 100 0 250 0 300
H = 1×7
4 2 0 5 0 0 1
T = 1×7
7 9 12 4 9 4 12
idx = D == 0;
D(idx) = [];
H(idx) = [];
T(idx) = [];
D,H,T
D = 1×3
100 250 300
H = 1×3
0 0 1
T = 1×3
12 9 12
