iFit/cat

PURPOSE

SYNOPSIS

DESCRIPTION

 s = cat(dim,a,...) : catenate iData objects elements along dimension

   @iData/cat function to catenate iData objects elements along dimension dim
     cat(dim,a,b,c,...) catenates along axis of rank dim. The axis is then extended.
     cat(1,a,...) accumulates on first dimension (columns)
     cat(a,b...)  accumulates on first dimension (columns) (uses dim=1)
     cat(0,a,...) catenates objects along a new dimension (dim = ndims(a)+1)

 input:  a: object or array (iData/array of)
         dim: dimension to accumulate (int)
 output: s: catenated data set (iData)
 ex:     c=cat(1,a,b); c=cat(1,[ a b ]);
