Hello!

I am trying to create variable names automatically, such as:

Name_1

Name_2

Name_3

...

Name_N

To assign a different value to each one.

Do you know how to do it, any idea?

may be field names are a solution

define an empty struct

myStruct = []

and add fieldnames dynamically

myStruct.(<varName>) = myVal

@chrisw23: given the sequentially-numbered names shown in the original question, basic indexing would be simpler and much more efficient.

在 MATLAB Online 中打开

NameIndex=1;
Value=2;
eval(sprintf('Name_%u=%d',NameIndex,Value));
Name_1 = 2

This is possible by eval but as mentioned in the comments section, it is not recommended if there is not a very good reason.

The name "MATLAB" comes from "MATrix LABoratory", i.e. it is designed to work efficiently with arrays and indexing. Indexing is a MATLAB superpower. If you do not use indexing, then using MATLAB will be... difficult. The name "MATLAB" does not come from "lets store the data in lots and lots of separate variables and make our data harder to work with":
