i need to delete a zero from a single row 10 column vector

how can i delete this first 0

1.0e+03 *

0 1.0794 0.9376 0.8301 0.7477 0.6838 0.5939 0.5366 0.4988 0.4732

so it would look like this

1.0e+03 *

1.0794 0.9376 0.8301 0.7477 0.6838 0.5939 0.5366 0.4988 0.4732

Answer 1

[Stephan]

A = [0 1 2 3 0 5]
A = A(A~=0)

Or, the other Matlab idiom you'll see is

A(A==0)=[];

Or, to answer the original question with the qualifier of "only first zero" in Stephan's example data,

A(find(A==0,1))=[];

as the other two will eliminate all zeros, not just first...

Thnak you!!

To delete the first zero entry ONLY:

A(find(A==0,1,'first'))=[];

To delete only the FIRST zero (not all zeros) here is one way.

indexes = find(v == 0);
if ~isempty(indexes)  % Only try to delete if we actually FOUND a zero!
    v(indexes(1)) = []; % Do the deletion.
end

[madhan ravi]

    v(indexes(1) = []; % Do the deletion.
                ^--- missed a paranthesis

You're right - thanks - fixed.

As we've covered the other cases pretty thoroughly...

For the specific input vector OP showed where it is almost certain it is known a priori the first value in the array is zero from outside knowledge of what created the vector in the first place, simply

A=A(2:end);
