Problem 1 Write your code in the file MatrixOps.java. . Consider the following definitions from matrix algebra: A vector is a one-dimensional set of numbers, such as [42 9 20]. The dot product of two equal-length vectors A and B is computed by multiplying the first entry of A by the first entry of B, the second entry of A by the second entry of B, etc., and then summing these products. For example, the dot product of [42 9...

1. 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.
2. 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 i and j and the scalar was m,...
