WebQuestion No. 1: Write a function that multiplies two matrices and returns the resulting matrix as output. The function should take two input arguments. The inputs could be row vectors, column vectors, matrices or a combination of these. The function should check if matrix multiplication is possible. WebUse. p = polyfit (t,y,2); fit = polyval (p,t); plot (u,g,'-',t,y,'o',t,fit) The first line is the built-in polynomial fit function. The number 2 is the degree which you specify and it returns the coefficients of the polynomial in p. Note degree 2 means three coefficients. The second line then evaluates the polynomial using the coefficients in p.
