Write a matlab code that asks the user to enter the binary and gray values and then convert binary to gray and vice versa.

E. The postfix form of the expression; A*B+C/D is: A АB/CD+ B A *BC+/D AB*CD/+ D ABCD+/*

what is invalid input ?

Please use C++ In this lab, you need to write a program which, given a seven digit binary input given below, it will check to see if there is a single bit error using the Hamming Code method discussed in lab. For a sample of Hamming Code, the input: 1110101 will reveal that ‘110’ is the location of the error (meaning the sixth slot in the input), so the corrected number would be 1010101, and the actual message transmitted, would be 1011, which is 11 in decimal. You can use this example to test your program to ensure it’s working correctly. Create a program which can, given a 7-bit long input, written in Hamming Code style, do the three following tasks, displaying the results as output.             (1) Determine if there’s an incorrect bit, and if so, where it is.             (2) Display what the CORRECT code should look like (if it needs to be corrected.)             (3) Display the decimal form of the message that was sent, after any needed correction. Remember, when using Hamming…
