Deterrnine tras and for the folowing values of stress -140 MPa -250 MPa Try = 100 MPa Question 5 Create the following matrix E 0.7 0.6 0.5 04 0.3 02 0.1 246810 12 22 19 16 13 10 74 through the seventh a. Create a 2 x 5 matrix F from the second and fourth rows, and the third columns of matrix E b. Create a 4 x 3 matrix G from ali rows and the second through fourth columns of matix E c. Without re-entering any values find the product of Ess and E d. Using zeros, ones, and eye commands create the tollowing array 010010 0010o 1001o

Explanation / Answer

part c)no of columns of the 1st matrix must equal the number of rows of the 2nd matrix.

the result will have the same number of rows as the 1st matrix, and the same number of columns as the 2nd matrix.

So here,E32 and E46 means

first matrix contains 3 Rows and 2 columns and

Second Matrix contains 4 rows and 6 columns so,here no of columns of the first matrix not equal to the number of rows of the second matrix so product of the two matrices are not possible
