Please make sure to not use the : operator for any of these. Thank you.

2. Write a MATLAB function that takes a matrix, a row number and a scalar as arguments and multiplies each element of the row of the matrix by the scalar returning the updated matrix. Use loops for the program. Do not use the : operator. 3. Write a MATLAB function that takes a matrix, two row numbers and a scalar as arguments and returns a matrix with a linear combination of the rows. For example, if the rows passed to the function were tand, and the scalar was , each element of row/ would become ak + ak where k represents columns 1 through the number of columns in the matrix. Use loops for the program. Do not use the : operator
