How can I generate variable names automatically based on my data?

I want to create multiple variables to the Workspace such as: 'x1', 'x2', 'x3', ... and so on depending on how long my data is.

How can I do this in MATLAB?

You can use the "assignin" function in a for loop to do this:

>> for i = 1:5
>>     assignin('base',strcat('x',num2str(i)),i);
>> end

[Stephen23]

The assignin help states "Assigning to variables in the caller workspace can make code more difficult to understand, give surprising results to the user (unexpected or redefined variables in their workspace), and have a negative performance impact. The best practice is to have the function return the variables as output arguments."-

The Share Data Between Workspaces page states "Like global variables, these functions carry risks of overwriting existing data. Use them sparingly.... For other programming applications, consider argument passing and the techniques described in Alternatives to the eval Function."
