Creating a *.mat file
显示 更早的评论
Hello, I want to create a *.mat file, for example named bathymetry. This array called bathymetry I want to be formed by 3 other arrays, for example, x, y and z. In a way, that when I charged the mat file it transforms into three files called x, y and z.
I've tried my easy way: for example: bathymetry=[x,y,z], but when I charged it, it's only 1 file called bathymetry and I want to have them separetely.
Please help me.

Do you mean this?
% Create some variables
x = rand(3);
y = magic(3);
z = eye(3);
% Save the variable x,y,z into one *.mat file
save bathymetry.mat x y z
% Clear them out of the workspace
clear x y z
% Load them again
load bathymetry.mat

What is a .xyz file?
Also, I suggest you open a new question, with full details of your question, instead of burying your question as a comment in a year-old thread. It was pure luck that I happened to stumble on your comment.

Machine Learning & Power Systems Ali: we are going to need more detail than that. What is your code, and what is your exact error message?

I already tried with load and audioread and so on. Than I tried that sound convert in .wav and he still does not recognize that file. When I put for example load pcela.wav % pcela.wav is my name of that recorded sound Error using load Unknown text on line number 1 of ASCII file pcela.wav "RIFF’_".
Am I doing something wrong? Please help me I don't have no idea anymore and I cant find anything similar on web.

That typically means that you don't have write permissions in the current directory. Move to somewhere else (cd...) and try again.

You are probably cd'd to a directory that is underneath the MATLAB installation. The directory that MATLAB starts executing in is not necessarily your personal MATLAB directory.

Check the following code for the path of the current Matlab folder
path = pwd
use 'cd' to change it to another folder with write access.
usually, the default folder for Matlab code in most cases is" 'C:\Users\xxx'"
changing it to another drive solves this

First define a file name with its location
saveFileName='datafiles\filename2.mat';
next use below code to create an empty .mat file
save(saveFileName);
