sliceShape

Compute the shape of a normalized multi-slice.

Usage

var sliceShape = require( '@stdlib/slice/base/shape' );

sliceShape( slice )

Returns the shape of a normalized multi-slice.

var S = require( '@stdlib/slice/ctor' );
var MultiSlice = require( '@stdlib/slice/multi' );
var normalizeMultiSlice = require( '@stdlib/slice/base/normalize-multi-slice' );

var s = new MultiSlice( S( -4, null, -1 ), S( 2, 10, 1 ) );
// returns <MultiSlice>

s = normalizeMultiSlice( s, [ 10, 10 ], false );
// returns <MultiSlice>

var sh = sliceShape( s );
// returns [ 7, 8 ]

Examples

var S = require( '@stdlib/slice/ctor' );
var MultiSlice = require( '@stdlib/slice/multi' );
var normalizeMultiSlice = require( '@stdlib/slice/base/normalize-multi-slice' );
var sliceShape = require( '@stdlib/slice/base/shape' );

var s1 = new MultiSlice( S( 3, null, -1 ), S( 3, 7, 1 ) );
var s2 = normalizeMultiSlice( s1, [ 10, 10 ], false );
var sh = sliceShape( s2 );
console.log( '%s => %s', s1.toString(), s2.toString() );
console.log( '[ %s ]', sh.join( ', ' ) );
// => '[ 4, 4 ]'

s1 = new MultiSlice( null, S( -1, -8, -2 ) );
s2 = normalizeMultiSlice( s1, [ 11, 12 ], false );
sh = sliceShape( s2 );
console.log( '%s => %s', s1.toString(), s2.toString() );
console.log( '[ %s ]', sh.join( ', ' ) );
// => '[ 11, 4 ]'

s1 = new MultiSlice( S( null, null, 1 ), null );
s2 = normalizeMultiSlice( s1, [ 11, 12 ], false );
sh = sliceShape( s2 );
console.log( '%s => %s', s1.toString(), s2.toString() );
console.log( '[ %s ]', sh.join( ', ' ) );
// => '[ 11, 12 ]'

s1 = new MultiSlice( S( 5, 5, 1 ), null );
s2 = normalizeMultiSlice( s1, [ 11, 12 ], false );
sh = sliceShape( s2 );
console.log( '%s => %s', s1.toString(), s2.toString() );
console.log( '[ %s ]', sh.join( ', ' ) );
// => '[ 0, 12 ]'

s1 = new MultiSlice( S( 5, 5, 1 ), S( 3, 3, 1 ) );

sh = sliceShape( s2 );
console.log( '%s => %s', s1.toString(), s2.toString() );
console.log( '[ %s ]', sh.join( ', ' ) );
// => '[ 0, 0 ]'
