how convert hex character into equivalent decimal number ?

Hi , i have hex number as character form , i need read its as equvialent number such as :

'B' = 11

'A' = 10

'8' =8

how can read them as decimalnumber plaease ?

clc;
b1 = hex2dec('000fff0');
b = hex2dec ('6e4efb');
format hex;
 x=bitand(b1,b )
cc=dec2hex(x)
bin=hexToBinaryVector(cc)
 cc=bin(end-flip(7:10)+1)
 bp=num2str(cc)
 bp1= bp(find(~isspace(bp))),
 hex_str = dec2hex(bin2dec(bp1))
 bank1= str2num(hex_str)

hex2dec() like you do now is correct.

Do you perhaps want to translate them digit by digit? If so then

sscanf('000fff0', '%1x', [1 inf])

Thanks alot for your helping.

i apologize but it still when i used hex2dec() gave me :

'B' = 4026000000000000 !!!!

it should be 'B'=11

clc;
b1 = hex2dec('000fff0');
b = hex2dec ('6e4efb');
format hex;
 x=bitand(b1,b )
cc=dec2hex(x)
bin=hexToBinaryVector(cc)
 cc=bin(end-flip(7:10)+1)
 bp=num2str(cc)
 bp1= bp(find(~isspace(bp))),
 hex_str = dec2hex(bin2dec(bp1))
   bank1= hex2dec(hex_str)

??

You seem to be saying that after you do

b = hex2dec ('6e4efb');

that you want b to be decimal 11 ?? Even though you assigned a completely different value to b ??
