load
Retrieve variables from disk
load loadThefilename load (filename)
load filename.ext
load filename -ascii
load filename -mat
load
and save
commands retrieve and store MATLAB variables on disk.
load
by itself, loads all the variables saved in the file 'matlab.mat'
.
load filename
retrieves the variables from 'filename.mat'
given a full pathname or a MATLABPATH
relative partial pathname .
load (filename)
loads a file whose name is stored in filename. The statements:
str = 'filename.mat'; load (str)retrieve the variables from the binary file
'filename.mat'
.
load filename.ext
reads ASCII files that contain rows of space separated values. The resulting data is placed into an variable with the same name as the file (without the extension). ASCII files may contain MATLAB comments (lines that begin with %
).
load filename -ascii
or load filename -mat
can be used to force load
to treat the file as either an ASCII file or a MAT file.
MAT-files are double-precision binary MATLAB format files created by the save
command and readable by the load
command. They can be created on one machine and later read by MATLAB on another machine with a different floating-point format, retaining as much accuracy and range as the disparate formats allow. They can also be manipulated by other programs, external to MATLAB.
The Application Program Interface Guide discusses the structure of MAT-files in detail. The Application Program Interface Libraries contain C and Fortran callable routines to read and write MAT-files from external programs.
fprintf
Write formatted data to file
fscanf
Read formatted data from file
save
Save workspace variables on disk
spconvert
Import matrix from sparse matrix external format
