Variable assignment in workspace

1 次查看(过去 30 天)
a=[1,2,3,4,5,6]
b=['c','d','e','f','g','h']
how can i assign the values to the variables that are present in array b and the values of those present in array a without hard coding the variable names.

Actually there is a excel sheet with list of variables in one column and list of value in another column. I want to assign those values to the variables in 1st column.

Why do you want to do that?
What would you do if the Excel file happened to name a variable that was the same as one of the variable names you were using to code the function?
... If you were to store everything into a struct like I demonstrated, then you would not have any conflicts.

The best approach is do not do that
For example, instead
a = [1,2,3,4,5,6]
a = 1×6
1 2 3 4 5 6
b = {'c','d','e','f','g','h'}
b = 1×6 cell array
{'c'} {'d'} {'e'} {'f'} {'g'} {'h'}
output = cell2struct(num2cell(a), b, 2)
output = struct with fields:
c: 1 d: 2 e: 3 f: 4 g: 5 h: 6

Thank Walter for your solution. Actually i wanted the variable to be assigned in the workspace.

If you are not effectively extending the syntax of MATLAB like syms or IBM's cvx, then what you are asking for is more trouble than it is worth, in the long run.
