General purpose exception class, derived from Python’s exception.Exception class, programmatically raised in linalg functions when a Linear Algebra-related condition would prevent further correct execution of the function. What is singular matrix? A square matrix is singular, that is, its determinant is zero, if it contains rows or columns which are proportionally interrelated; in other words, one or more of its rows (columns) is exactly expressible as a linear combination of all or some other its rows (columns), the combination being without a constant term. np.linalg.matrix_rank(cov) = 20 と，ランク落ち？をしてしまい，以下のエラーがでます． *** LinAlgError: singular matrix . おそらく，行列covのランクがlen(x), len(μ)と合っていないことが原因だと思うのですが， 行列のランク落ちを防いだりする方法はないでしょうか？ Correlation Matrix labels in Python. I'm using Python3The top of my matrix is a problem, all the labels are overlapping so you can't read them.
