What MATLAB can produce if the sequence of following statements are given >>pvec = 3:2:10 >>pvec(2) = 15 >>pvec(7) = 33 >>pvec(2:4, 7) >>linspace(5,11,5) >>logspace(2,4,3)

This command creates a vector pvec starting at 3, incrementing by 2, up to 10.

Output:

pvec =
     3     5     7     9

This command assigns the value 15 to the second element of pvec.

Output:

pvec =
     3    15     7     9

This command assigns the value 33 to the seventh element of pvec. Since pvec currently has 4 elements, MATLAB extends the vector and fills the intermediate elements (indices 5 and 6) with zeros.

Output:

pvec =
     3    15     7     9     0     0    33

This command displays the elements of pvec from index 2 to 4.

Output:

ans =
    15     7     9

This command generates a row vector of 3 linearly spaced points between 5 and 11 (inclusive).

Output:

ans =
     5     8    11

This command generates a row vector of 3 logarithmically spaced points between $10^2$ and $10^4$ (inclusive).

Output:

ans =
   100        1000       10000
