units of MPa). Using the set of experimental measurements below, write an M-file that uses nonlinear regression to fit a power relationship to the data(i.e. N = a *o", where a1 and a2 are the model constants to be determined). The M-file must then use the resulting power relationship to predict the number of cycles to failure at a stress level of 750 MPa. Plot the data points and the power relationship on a single plot. Be sure to label your axes. You may use the fminsearch function in your M-file to do the optimization (minimization) as discussed in the class for under Lecture 19 given as non linear regression (see the example script on Canvas script_nonlinear_regression_example.m). Provide a printout of your M-file and a printout of the command window showing your results.
