encoding - How to make MATLAB return char instead of ASCII? -

so, i'm using @ commands matlab return caller id, doesn't matter.

everything working great except fact returns ascii numbers , have take time "translating" ascii code char can know saying.

>> s = serial('com8'); >> fopen(s) >> fwrite(s, [65 84 43 67 82 67 61 49 13]) >> s     serial port object : serial-com8     communication settings        port:               com8       baudrate:           9600       terminator:         'lf'     communication state        status:             open       recordstatus:       off     read/write state         transferstatus:     idle       bytesavailable:     47       valuesreceived:     0       valuessent:         18  >> fread(s, 47) 

it returns me 47 ascii numbers this(note have deleted of returned code):

ans =      65     84     43     67     82     67     61     49     13 

i've tried following things:

char(fread(s,47)) 

and

z = fread(s,47) char(z) 

but neither of worked,

z = [65 84 43 67 82 67 61 49 13] char(z) 

works fine. suppose because fread returns ascii code newline between them , not space wrote in code above.

try str2double, str2num or subtract '0' ( ascii value of char '0' ) ascii code have.
