Detailed Description

Gets a reference to a set of elements.

    array A = array(seq(1,9), 3, 3);
    af_print(A);

    af_print(A(0));    // first element
    af_print(A(0,1));  // first row, second column

    af_print(A(end));   // last element
    af_print(A(-1));    // also last element
    af_print(A(end-1)); // second-to-last element

    af_print(A(1,span));       // second row
    af_print(A.row(end));      // last row
    af_print(A.cols(1,end));   // all but first column

    float b_host[] = {0,1,2,3,4,5,6,7,8,9};
    array b(10, 1, b_host);
    af_print(b(seq(3)));
    af_print(b(seq(1,7)));
    af_print(b(seq(1,7,2)));
    af_print(b(seq(0,end,2)));

This operator returns a reference of the original array at a given coordinate. You can pass af::seq, af::array, or an int as it's parameters. These references can be used for assignment or returning references to af::array objects.

Function Documentation

array::array_proxy operator()

(

const index &

s0

)

This operator returns a reference of the original array at a given coordinate.

You can pass af::seq, af::array, or an int as it's parameters. These references can be used for assignment or returning references to af::array objects.

If the af::array is a multi-dimensional array then this coordinate will treated as the data as a linear array.

Parameters

[in]

s0

is sequence of linear indices

Returns

A reference to the array at the given index

const array::array_proxy operator()

(

const index &

s0

)

const

This operator returns a reference of the original array at a given coordinate.

You can pass af::seq, af::array, or an int as it's parameters. These references can be used for assignment or returning references to af::array objects.

If the af::array is a multi-dimensional array then this coordinate will treated as the data as a linear array.

Parameters

[in]

s0

is sequence of linear indices

Returns

A reference to the array at the given index

array::array_proxy operator()	(	const index &	s0,
		const index &	s1,
		const index &	s2 = span,
		const index &	s3 = span
	)

This operator returns a reference of the original array at a given coordinate.

You can pass af::seq, af::array, or an int as it's parameters. These references can be used for assignment or returning references to af::array objects.

Parameters

[in]	s0	is sequence of indices along the first dimension
[in]	s1	is sequence of indices along the second dimension
[in]	s2	is sequence of indices along the third dimension
[in]	s3	is sequence of indices along the fourth dimension

Returns

A reference to the array at the given index

const array::array_proxy operator()	(	const index &	s0,
		const index &	s1,
		const index &	s2 = span,
		const index &	s3 = span
	)		const

This operator returns a reference of the original array at a given coordinate.

You can pass af::seq, af::array, or an int as it's parameters. These references can be used for assignment or returning references to af::array objects.

Parameters

[in]	s0	is sequence of indices along the first dimension
[in]	s1	is sequence of indices along the second dimension
[in]	s2	is sequence of indices along the third dimension
[in]	s3	is sequence of indices along the fourth dimension

Returns

A reference to the array at the given index
