    1)Write an m-file to find the area of the triangle for a given three corners of a triangle by using cross product in R^3.

    Hint: write a subfunction which evaluates the determinant of a matrix

    2)Write an m-file function which finds the rank and the nullity of a given mxn matrix. Do not use rank function of matlab. Write your own function.

    Hint: Reduce the matrix to a row echelon form and count the number of basis of column space or row space. Then use the theorem which states rank(A)+nullity(A)= number of columns of A

    Um, no thank you. Especially after I see the part that says "Write
    your own function." which I think applies to you rather than me.

    Oh, by the way, do you have a question?

    I think the question is implied:
    When can I expect my completed and professionally coded homework to be done for me?
