Detailed Description

The C++ interface for minmax.

Returns the minimum and the maximum value along a given dimension
or for all of the elements of an array.

float ha[] = {1, 2, 3, 4, 5, 6};
array in = array(2, 3, ha);
array minvals, maxvals;

minmax(minvals, maxvals, in, 0);
print(minvals);
print(maxvals);
// minvals = 1.0000    3.0000    5.0000
// maxvals = 2.0000    4.0000    6.0000

minmax(minvals, maxvals, in, 1);
print(minvals);
print(maxvals);
// minvals = 1.0000
//           2.0000
//
// maxvals = 5.0000
//           6.0000

Function Documentation

array af::minmax_packed	(	const array &	input,
		int	dim = -1
	)

Minimum and maximum (packed) of the elements along a dimension in matrix.

Parameters

[in]	input
[in]	dim	dimension along which to operate (-1 indicates first non-singleton dimension)

Returns

array of minimum (real part) and maximum (imag part) along the dimension dim in the input

void af::minmax	(	array &	minvalues,
		array &	maxvalues,
		const array &	input,
		int	dim = -1
	)

Minimum and maximum of the elements along a dimension in matrix.

Parameters

[in]	input
[in]	dim	dimension along which to operate (-1 indicates first non-singleton dimension)
[out]	minvalues	minimums
[out]	maxvalues	maximums

ty af::minmax

(

const array &

input

)

Minimum (out.x) and maximum (out.y) values among all elements in array.

int hx[] = { -3, -5, 2, -9 };
array x(2,2, hx); // 2x2 matrix
float2 extrema = minmax<float2>(x);
printf("%g,%g\n", extrema.x, extrema.y); // -9,2

Parameters

[in]

input

Returns

both minimum and maximum of all values in array
