1.Create a 100 X 100 random matrix (use the command randn) called B.

2.From B, create a matrix K which is a random matrix from a normal distribution with mean 4 and variance 16.

3.Create two vectors, v and z, which are respectively the first and the last row of K.

4.Plot v and z in the same graph, using as horizontal axis a vector t which contains the first 100 natural numbers.

5. The line of v must be red, a solid line, and the marker must be a circle. The line for z must be green, a dashed line, and the marker must be a star.

6. Add a legend to the plot.

This sounds like a homework assignment. If it is, show us what you've tried to solve the problem and describe specifically where you're having difficulty and we may be able to offer some guidance.

If you're not sure even where to start, I recommend either contacting your professor or teaching assistant or going through the tutorials in the Tutorials section on the Support webpage. The MATLAB Onramp tutorial should cover most if not all of the topics you'd need to complete that assignment.
