rename a variable

Question

0 个投票

in my workspace i have an array that is named 'data' and I have a name field with some filename = 'filename'

I would like to rename the array called data to the name that is stored in the filename name variable.

simply doing filename = data; renames data to filename not the actual name that filename holds.

Let me see if I interpret the question correctly: you have

filename = 'bob';
data = [1,2,3];

And you want to rename data to bob (the contents of filename)?

Firstly, be careful doing things like this. It makes it very hard to track names. But, if you must...

str = [filename,'= data;'];
eval(str);

"if you must" then you probably have not written your program in a good way.

Baba, use dynamic structure field names of a single structure variable that will contain all of the data.
