maxc#
Purpose#
Returns a column vector containing the largest element in each column of a matrix.
Format#
- y = maxc(x)#
- Parameters:
x (NxK matrix or sparse matrix) – data
- Returns:
y (Kx1 matrix) – contains the largest element in each column of x.
Examples#
// Create random x
x = rndBeta(4, 2, 3, 1);
// Find maximums in each column
y = maxc(x);
If x equals:
0.87174453 0.70281291
0.90393029 0.95919009
0.82960656 0.58022236
0.80910492 0.61975567
then y will equal:
0.90393029
0.95919009
Remarks#
If x is complex, maxc() uses the complex modulus (abs(x)) to determine the
largest elements.
To find the maximum elements in each row of a matrix, transpose the
matrix before applying the maxc() function.
To find the maximum value in the whole matrix if the matrix has more
than one column, nest two calls to maxc():
y = maxc(maxc(x));
