Error using vertcat Dimensions of matrices being concatenated are not consistent.

this error occur when make lines connecting center and points buy this code

% make lines connecting center and points

       x00 = [xyr([1 1 1]) ; px ; xyr([1 1 1])] ;

       y00 = [xyr([2 2 2]) ; py ; xyr([2 2 2])] ;

• xyr vector of two points that i want to connect and the radius

*px and py coordinates of points

>> px

px =

     3
     8
    10

>> py

py =

   791
   388
   570

and

>> xyr([1 1 1])

ans =

   1.0e+03 *

   -4.7159   -4.7159   -4.7159

>> xyr([2 2 2])

ans =

530.9219  530.9219  530.9219

Any idea please!

thak you.

You're trying to write the equivalent of

Z = [1 2 4; ...
     3    ; ...
     8    ; ...
     9    ; ...
     8 5 2];

Can't do that unless Z is a cell array containing two 3x1 and a 1x3 array.

You needs must write

x00 = [xyr(1,1,1) ; px.' ; xyr([1 1 1])] ;

or create px as a row vector instead of column to have a square array.

As said, not sure what you then intend to do with the result; from looking at the data values doesn't look to me quite like what line input array likely is needing to be, but this solves your concatenation problem first; can look at the result next.

hello,

Still the same error

any other idea please !

Oh, senior moment, sorry. Forgot px is already a vector just oriented wrong...edit in previous answer.

thank you a lot

you make my day
