How to remove zeros from a vector and remove values from those indices in a corresponding vector?

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.

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
