Description

Reads the values in a mat-file to a list.

Usage

1
read.mat(filename)

Arguments

filename

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.

Note

  • A sparse complex matrix is read as a dense complex matrix.

  • 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

  • A structure is read as a named list with fields.

  • A cell array is read as an unnamed list with cell data

  • A function class type is read as NULL and gives a warning.
