Type	Description
Matrix | Array	Squeezed matrix

Examples

math.squeeze([3]);           // returns 3
math.squeeze([[3]]);         // returns 3

var A = math.zeros(3, 1);    // returns [[0], [0], [0]] (size 3x1)
math.squeeze(A);             // returns [0, 0, 0] (size 3)

var B = math.zeros(1, 3);    // returns [[0, 0, 0]] (size 1x3)
math.squeeze(B);             // returns [0, 0, 0] (size 3)

// only inner and outer dimensions are removed
var C = math.zeros(2, 1, 3); // returns [[[0, 0, 0]], [[0, 0, 0]]] (size 2x1x3)
math.squeeze(C);             // returns [[[0, 0, 0]], [[0, 0, 0]]] (size 2x1x3)
