• a function that returns a vector
• a function that creates a random vector
• a function that returns a matrix
• a function that creates a random matrix
• a function that return the space we took from the memory to the system
• a function that calculates mean
• a function that calculates correlation
• a function that calculates covariance
• a function that calculates the multiplication of a matrix
• a function that calculates the transpose of a matrix
• a function that calculates the row means
• a function that calculates the column means
• a function that calculates the covariance of a matrix
• a function that calculates the determinant of a matrix
• a function that prints the vector
• a function that prints the matrix
