3) When a row vector a (1xn) is multiplied to a column vector b (nx1), the result is a scalar (1x1). This is called the inner product, also called the dot product or scalar product. 32 is1 MATLAB can perform this efficiently using multiplication, or the built-in function dot. Write a MATLAB function M-file named inner.m to compute the inner product using a for loop. The input to the function should be a and b as shown below, and the output should be the dot product. Your function should halt with a red error message if dimensions of the input vectors are not a row vector& column vector with a matching inner dimension Publish the sample case as inner.pdf For example: >> inner ( [4 25 1], (3;6;1;2)) ans- Passed Cody tests 31
