Since ASCII characters are encoded as unsigned 8-bit integers, you can store them as a UINT8 data type in MATLAB. You can use the UINT8 function to get the ASCII values of a character string.
>> a='ABCabc!@#$%^&*()-+'
a =
ABCabc!@#$%^&*()-+
>> uint8(a)
ans =
65 66 67 97 98 99 33 64 35 36 37 94 38 42 40 41 45 43

Only if it is US-ASCII ;-)
There were a number of different ASCII. For example, in the UK version of ASCII, the position held by '$' is the pound sign.

Possibly the answer you are looking for is str2double()
