Solution:

The output of the following sequence of statements and expressions:

“mat = [1:3; 44 9 2; 5:-1:3]”, “mat(3, 2)” “mat(2,:)”, “size(mat)”, “mat(:, 4) = [8;11;33]”, “numel(mat)”, “v = mat(3,:)”, “v(v(2))”, “v(1) = []”, and “reshape(mat, 2, 6)” are “mat=[1234492543]”, “ans = 4”, “ans = 44 9 2”, “ans = 3 3”, “mat=[123844921154333]”, “ans = 12”, “5 4 3 33”, “ans = 33”, “v = 4 3 33”, and “[159331144242833]” respectively.

Consider the following statement,

mat = [1:3; 44 9 2; 5:-1:3]

The statement will generates the matrix with the elements of the row with 1, 2, 3; second row 44, 9, 2; and the third row with 5, 4, 3.

So, the output is “mat=[1234492543]”

Consider the following statement,

mat(3, 2)

This command generates the value that is placed at third row and second column of the matrix “mat”.

So, the output is “ans = 4”.

Consider the following statement,

mat(2,:)

This command generates the second row elements of the matrix “mat”.

So, the output is “ans = 44 9 2”.

Consider the following statement,

size(mat)

This command generates the order of matrix.

So, the output is “ans = 3 3”.

Consider the following statement,

mat(:, 4) = [8;11;33]

This command includes the fourth column to the matrix “mat”.

So, the output is “mat=[123844921154333]”.

Consider the following statement,

numel(mat)

This command generates the number of elements present in the matrix “mat”.

So, the output is “ans = 12”.

Consider the following statement,

v = mat(3,:)

This command generates the third row elements from the matrix “mat”.

So, the output is “5 4 3 33”.

Consider the following statement,

v(v(2))

Since, v(2)=4 for the matrix “mat”, the output will be v(4) that is 33.

So, the output is “ans = 33”.

Consider the following statement,

v(1) = []

This command generates the elements of “v” eliminating the first elements.

So, the output is “v = 4 3 33”.

And consider the following statement,

reshape(mat, 2, 6)

This command changes the order of the matrix from 3×3 to 2×6.

So, the output is “[159331144242833]”.
