Multiply vector by scalar matlab
WebI have an array X with dimension mxn, for every row m I want to get a correlation with a vector y with dimension n. In Matlab this would be possible with the corr function corr(X,y). For Python however this does not seem possible with the np.corrcoef function: Which results in shape (1001, 1001).

WebGiven vectors u = (5, 4) and v = (3, 9), we are asked to find 6u - 4v. This requires us to perform scalar multiplication and subtraction on these vectors. Scalar multiplication is the process of multiplying each component of a vector by a scalar (a single number). In this case, we need to find 6u and 4v. Multiply u by scalar 6: 6u = 6 * (5, 4) busby investmentsWebCreate two vectors, A and B, and multiply them element by element.
