name of variables from a cell of strings

Let b={'alpha', 'beta', 'gamma'}

What is the best way to generate variables whose name contains each element of b? For example how do I generate variables x_alpha, x_beta, x_gamma? from b?

[Star Strider]

Please don’t!

Make arrays out of them instead.

Answer 1

b={'alpha', 'beta', 'gamma'}
c=cellfun(@(x) ['x_' x],b,'un',0)

Look at

If you just want to add a 'x_' before every string of b, you're way better off using the dedicated function STRCAT.

b = {'alpha', 'beta', 'gamma'}
c = strcat('x_', b)

But still, dot not use these a variable names! Use structs instead.

Answer 2

[Jos (10584)]

Do not do this! Use structs

b={'alpha', 'beta', 'gamma'}

x.(b{1}) = 1:3
x.(b{2}) = 'hello'
x.(b{3}) = NaN
