Question

I am trying to insert a value into Matlab vector like this:

 P = [ P(1:pos) point P(pos+1:end-1) ];

Yet I keep getting this error:

??? Error using ==> horzcat
CAT arguments dimensions are not consistent.

Error in ==> main at 65
 P = [ P(1:pos) point P(pos+1:end-1) ];

There is end-1 because I red that error above have something to do with arrays limits mismatch.

P.S. I know that value insertion into arrays is pretty common issue yet this seams to be the simplest way to do it and I really would like to understand why it would not work.

Answer 1

This statement is attempting to concatenate horizontally

P = [ P(1:pos) point P(pos+1:end-1) ]

But your vector P is a column vector.

What you need is a row vector, so transpose P first

P=P';
