// Description:
|
||||
// If given a number, returns the square of that number,
|
||||
// If given a vector, returns a vector of the squares of each element in the input vector.
|
||||
// If given a vector, returns the sum-of-squares/dot product of the vector elements.
|
||||
// If given a matrix, returns the matrix multiplication of the matrix with itself.
|
||||
// Examples:
|
||||
// sqr(3); // Returns: 9
|
||||
// sqr(-4); // Returns: 16
|
||||
// sqr([3,4]); // Returns: [9,16]
|
||||
// sqr([2,3,4]); // Returns: 29
|
||||
// sqr([[1,2],[3,4]]); // Returns [[7,10],[15,22]]
