hi every one, i need help to make something in matlab that i don't if it can be done or not , thank you

A=[ 5 4 9 0 0 1 3 8 2 1 ]

B=[ 0 0 1 3 2 5 8 0 0 2 ]

C=[ 6 3 0 5 7 3 1 3 4 0 ]

if n=1:10

X=[ A ; B ; C] % in need this when all value are difference from zero so i need an output 3x10

X=[ A; B] % when value of C is zero i need output 2x10

X=[ A ;C] %% when value of B is zero i need output 2x10

X=[ B ;C] %% when value of A is zero i need output 2x10

so what i need in the code is when the value of the element of a vector is zero , i dont want to consider it inside the loop , always with the same variabile if it possibile

thank you

Try this:

It uses:

X = X(~all(X == 0,2),:)                         % Deletes Zero Rows

to delete the rows that are all 0.

For example:

A=[ 5 4 9 0 0 1 3 8 2 1 ];
B=[ 0 0 1 3 2 5 8 0 0 2 ];
C=[ 6 3 0 5 7 3 1 3 4 0 ];

X = [A; zeros(size(A)); C]
X = X(~all(X == 0,2),:)                         % Deletes Zero Rows

producing:

X =
     5     4     9     0     0     1     3     8     2     1
     6     3     0     5     7     3     1     3     4     0
