mot566_sum (Motorola DSP Developer's Kit)

mot566_sum

Sum the elements of a matrix along rows or columns.

MATLAB Syntax

Y=mot566_sum(X)
Y=mot566_sum(X,DIM)

Description

For vectors, mot566_sum(X) is the sum of the elements of X. For matrices, mot566_sum(X) is a row vector with the sum over each column.

mot566_sum(X,DIM) sums along the dimension DIM.

Characteristics

In the workspace, if

 X = [0   0.1 0.2
      0.3 0.4 0.1]

then

 mot566_sum(X,1) = [0.3 0.5 0.3]
 mot566_sum(X,2) = [ 0.3
                     0.8]

Argument
X
Vector (or matrix) with elements normalized in the range [-1,1] (for complex elements, both real and imaginary parts should comply with this limit).

Y
The sum result of input.
