Hi guys
I have a string like this: 'Address: 0x050 Value: 0xEC'
I am recieving the string from a device, so i cant change the format of the numbers.
I want to extract the hexadecimal numbers from the string and convert them to decimal numbers!
How can i do this?
thx.

s = 'Address: 0x050 Value: 0xEC';
out = sscanf(s,'Address: %x Value: %x');
This includes the conversion from hex to dec.

Depending on how consistent the placement of the hex value is, you might be able to simply use
s = 'Address: 0x050 Value: 0xEC';
hexValue = s(10:14);
but you might have to resort to using the regexp() command to extract the hex strings.
After you extract the hex string, you can use the function hex2dec() to convert it to a decimal value.

s = 'Address: 0x050 Value: 0xEC';
c = textscan(regexprep(s,'0x',''),'%s\t%s\t%s\t%s');
Address = hex2dec(c{2});
Value = hex2dec(c{4});
