Character string, with the MAT file or URL to read.

Details

Reads the values in a mat-file and stores them in a list.

Value

A list with the variables read.

• A sparse logical matrix is read as a 'lgCMatrix'

• A sparse matrix is read as a 'dgCMatrix'

• A matrix of dimension 1 x n or n x 1 is read as a vector
