I really do like this forum. But sometimes I suggest to take the time to search in the net. You can imagine, that this problem has been solved by others already. You find the general algorithm at WikiPedia and most likely your textbook for maths. When you search for "Matlab convert hex to base" you will even find running Matlab code.

Hello Mohammad Imam Malik,
I guess you are asking for the principle behind these conversions.
Steps:(Decimal to hex)
1. Divide the decimal number by 16. Treat the division as an integer division.
2. Write down the remainder (in hexadecimal).
3. Divide the result again by 16. Treat the division as an integer division.
4. Repeat step 2 and 3 until result is 0.
5. The hex value is the digit sequence of the remainders from the last to first.

Use a string (1xN char) to store the values. Either generate the string using their character codes, or select the characters from a vector using indexing, or simply call sprintf with one of the hex formats.
