Quaternion Function Reference

cat

Concatenate arrays
(Quaternion overloading of standard MATLAB® function)

Syntax

r = cat(dim, varargin)

Description

cat concatenates arrays along a specified dimension, given by dim. Quaternion arrays may be concatenated with non-quaternion arrays provided the non-quaternion arrays are numeric. The non-quaternion arrays will be converted to quaternion arrays by supplying a zero vector part.

Examples

>> q = cat(2, eyeq(2), randq(2))
 
q =
 
     2x4 quaternion array
 
>> show(q)
 
q.S =
 
    1.0000         0   -0.3181    0.9194
         0    1.0000    0.1766   -0.0854

q.X =
 
         0         0   -0.2900   -0.1664
         0         0    0.2511   -0.2816

q.Y =
 
         0         0   -0.2381    0.2980
         0         0   -0.2083   -0.1756

q.Z =
 
         0         0    0.8706    0.1954
         0         0    0.9287    0.9394
