1 FUNCTION WITH SINGLE VARIABLE (8x7-56) - Create MATLAB functions to evaluate the following mathematical func- tions (make sure you select meaningful function names) and test them. To test your functions you'll need to call them from the command window, or use them in a script M-file program. Remember, each function requires its own M-file. 1. y(x) 2, y(x) = d/x 3. (x) sin () Create MATLAB functions for the following unit conversions (you may need to consult a textbook or the Internet for the appropriate conversion factors). Be or by using them in a script M-file program sure to test your functions, either from the command window 4. Inches to feet 5. Calories to joules 6. Watts to BTU/hr 7. Meters to miles 8.
