/**
|
|
* Test element wise whether two matrices are equal.
|
|
* The function accepts both matrices and scalar values.
|
|
*
|
|
* Strings are compared by their numerical value.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.deepEqual(x, y)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.deepEqual(2, 4) // returns false
|
|
*
|
|
* a = [2, 5, 1]
|
|
* b = [2, 7, 1]
|
|
*
|
|
* math.deepEqual(a, b) // returns false
|
|
* math.equal(a, b) // returns [true, false, true]
|
|
*
|
|
* See also:
|
|
*
|
|
* equal, unequal
|
|
*
|
|
* @param {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} x First matrix to compare
|
|
* @param {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} y Second matrix to compare
|
|
* @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix}
|
|
* Returns true when the input matrices have the same size and each of their elements is equal.
