Use a variable in Request user input prompt.

I am trying to use the Request User Input command with a changeable message for every iteration. For example:

1 prompt=sprintf('For file %f give the value for x',filename)
2 x = input(prompt)

However filename is a 1x23 char and I don't get the result I get. The code I use, treats filename as a

Any solutions?

The identifier you are using in sprintf (%f) stands for floating point, but you want a char array so use the identifier %s.

>> filename = 'abcdef.csv';
>> prompt=sprintf('For file %s give the value for x',filename)
prompt =
For file abcdef.csv give the value for x
