i have a struct loaded and one of it's fields contains names such that struct(1).name contains "First" struct(2).name containis "Second" and so on
I would like to use these struct fields as a variable in my code. For example I'd like to set struct(1).name=content of some matrix so instead of saying X=[1;2;3] i'd like to say struct(1).name=[1,2,34] so First=[1,2,34] would be stored in the workspace. I just don't know how i need to convert struct(i).name to be able to use it

Creating variables dynamically is prone to errors, hard to debug and slows down Matlab. Therefore it is recommended to avoid this.
A more efficient approach is using dynamic fieldnames:
data.(struct(1).name) = [1, 2, 34];
data.(struct(2).name) = [1, 2, 34];
Then the new variables are encapsulated in the struct data.

This will do what you described.
structVar(1).name = 'First';
structVar(2).name = 'Second';
makeVarFun = @(str, val) assignin('caller', genvarname(str), val);
for i = 1:numel(structVar)
varName = structVar(i).name;
