1. In lecture we defined our own 8-bit floating-point number definition with the following attributes: First bit represents the sign of the number .Bits 2-4 represent the signed exponent Bits 5-8 represent the mantissa Write a MATLAB function called my8BitNumber.m that takes a string representation of an 8-bit floating-point number as an input argument and returns the base-10 equivalent. a. e.g. >>inputStr'01101010 (Hint: use the st r2num function) A "skeleton code" outline of your function can be downloaded from Canvas. b. Test your code with the following floating-point numbers. Verify the results by hand: 01101010 11101010 01101100 00101100
