var linspace2d = require( '@stdlib/array/base/linspace2d' );

Generates a linearly spaced two-dimensional nested numeric array.

var x = linspace2d( 0, 100, [ 2, 3 ], false );
// returns [ [ 0, 20, 40 ], [ 60, 80, 100 ] ]

x = linspace2d( 0, 100, [ 2, 3 ], true );
// returns [ [ 0, 40, 80 ], [ 20, 60, 100 ] ]

The function accepts the following arguments:

• start: first array value.
• stop: last array value.
• shape: array shape.
• colexicographic: specifies whether generated array values should be stored in colexicographic order.

• The output array is guaranteed to include the start and stop values. Beware, however, that values between start and stop are subject to floating-point rounding errors. Hence,

  var arr = linspace2d( 0, 1, [ 1, 3 ], false );
  // returns [ [ 0, ~0.5, 1 ] ]

  where arr[0][1] is only guaranteed to be approximately equal to 0.5. If you desire more control over element precision, consider using roundn:

  var roundn = require( '@stdlib/math/base/special/roundn' );
  var map2d = require( '@stdlib/array/base/map2d' );
  
  var arr = linspace2d( 0, 1, [ 1, 3 ], false );
  // returns [ [ 0, ~0.5, 1 ] ]
  
  // Round each value to the nearest tenth:
  var out = map2d( arr, [ 1, 3 ], clbk );
  // returns [ [ 0, 0.5, 1 ] ]
  
  function clbk( v ) {
      return roundn( v, -1 );
  }
