Chapter 15, Problem 17ICA

For each of the following problems except part (h), write a single MATLAB statement that will accomplish the stated purpose.

a. Create a 150 × 150 matrix N9999 that contains all zeros except for the major diagonal (upper left to lower right). All elements on the major diagonal should contain the value -9999.

b. Create a 1200 × 1200 matrix p75 that contains all zeros except for the minor diagonal (lower left to upper right). All elements on the minor diagonal should contain the value 75.

c. Place the number of rows of matrix Ma into MaRows and the number of columns of matrix ma into maCols.

d. Assume matrix my. contains a single nonzero value. Place the row number containing this nonzero value into NZR and the column number into NZC.

e. Assume matrix Mz has already been defined. Place the row numbers of all elements in Mz that are negative into vector MzRN and the corresponding column numbers into MZCN.

f. Assume that matrix ms has already been defined. Place the elements on the major diagonal into row vector MSD.

g. Create a 5 × 9 matrix RM that contains random numbers chosen between -50 and +50.

h. Place the smallest value and the location within the matrix RM (created above) into MinRM. You may use more than one MATLAB statement to accomplish this task.
