Review Of Multiply 2 Matrix In Python References

Review Of Multiply 2 Matrix In Python References. A principal component analysis is carried out on a dataset comprised of three data points x1, x2 and x3 collected in a n × m matrix x such that each row of the matrix is a data point. For example x = [ [1, 2], [4, 5], [3, 6]] would represent a 3x2 matrix.
