minc#
Purpose#
Returns a column vector containing the smallest element in each column of a matrix.
Format#
- y = minc(x)#
- Parameters:
x (NxK matrix or sparse matrix) – data
- Returns:
y (Kx1 matrix) – contains the smallest element in each column of x.
Examples#
// Create random matrix
x = rndn(4, 2);
// Find minimum in each column
y = minc(x);
If x is equal to:
-1.9950 -1.3477
-0.4031 -1.9137
0.8136 -2.3155
-0.9947 1.4061
then y will equal:
-1.9950
-2.3155
Remarks#
If x is complex, minc() uses the complex modulus (abs(x)) to determine the
smallest elements.
To find the minimum element in each row, transpose the matrix before
applying the minc() function.
To find the minimum value in the whole matrix, nest two calls to minc():
y = minc(minc(x));
