Matrix
Select a function from the list below.
Icon | Name | Description |
---|---|---|
AddMatrices | Add two matrices of identical dimensions | |
ApplyPCATransformation | Applies previously obtained PCA transformation coefficients to new data. | |
CombineMatrices | Combine two matrices horizontally | |
ConcatenateMatrices | Combine two matrices horizontally | |
CreateIdentityMatrix | Create a square matrix with ones on the main diagonal, and zeros elsewhere. | |
CreateUniformMatrix | Create a matrix with the specified dimensions and filled with an uniform element value. | |
InvertMatrix | Find the inverse of a square matrix. | |
LoadMatrix | Loads serialized Matrix object from avdata file. | |
MatrixDeterminant | Find the determinant of a square matrix. | |
MatrixPseudoEigenvectors | Find the pseudo-eigenvalues and pseudo-eigenvectors of a symmetrical square matrix. | |
MultiplyMatrices | Combine two matrices horizontally | |
MultiplyMatrixByReal | Multiply all elements of a matrix by a value. | |
NormalizeMatrixData | Treats Matrix as a data frame, where examples are in rows while columns represent features, and normalizes the data by subtracting mean from each column and dividing it by its standard deviation. | |
