mot563_min (Motorola DSP Developer's Kit)

Find the minimum value and index of one or two input vector(s).

MATLAB Syntax

N=mot563_min(X,Y)
N=mot563_min(X,DIM)
[N,I]=mot563_min(X,DIM)

Description

For vectors, mot563_min(X) is the smallest element in X. For matrices, mot563_min(X) is a row vector containing the minimum element from each column.

[N,I] = mot563_min(X) returns the indices of the minimum values in vector I.

If the values along the first non-singleton dimension contain more than one minimal element, the index of the first one is returned.

mot563_min(X,Y) returns an array the same size as X and Y with the smallest elements taken from X or Y. Either one can be a scalar.

[N,I] = mot563_min(X,DIM) operates along the dimension DIM. When complex, the magnitude mot563_min(mot563_abs(X)) is used.

Characteristics

In the workspace, if the input is:

X=[0.4807 + 0.0000i   0.0319 - 0.2921i
   0.0000 + 0.6717i   0.5273 + 0.7144i]
Y=[-.1245 + 0.2242i   0.2623 - 0.7241i
   0.7800 + 0.1121i   -0.2324 ]

then the returned value is:

  N= mot563_min(X,Y)
  N=-0.1245 + 0.2242i   0.0319 - 0.2921i
     0 + 0.6717i        -0.2324

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

N
Vector or matrix with the same size as input, which consists of minimum value in every position.
