Question about store and obtain data in matlab.

Asked by C Zeng on 21 Jun 2012

Hello, I want to program to store a table of large size, does matlab support it and how to store the solution to a file?

When store it, I want to use those results in another project, how to obtain the data stored then?

For example, I want to store a 1000*5 matrix to a file, maybe a txt file. And I want to use the result by another file, how to obtain it? Thank you!

Hi, Walter, this is only for save data to a file(excel, csv, or txt), but how to read the file(matrix) and obtain the corresponding data?

Walter Roberson on 22 Jun 2012

Depends what the other project is implemented in. If it is in MATLAB then consider saving to a .mat file instead of a text file. If you choose not to do that but the other project is in MATLAB, then:
To read values from a file, use load() or importdata() or uiimport() or csvread() or xlsread() or dlmread() or textscan() or the basic I/O functions such as fgetl() and fscanf().
