Answer:)
By definition, is a row vector with only the ith component (column) non-zero i.e
Furthermore, if we multiply this with the stress matrix , we will get a row vector which corresponds to the ith row in the stress matrix. That is :
Eg, say we want to find this for i = 1:
Further, upon multiplying this row vector by the column vector , whose components are all zero except for the kth component (row), i.e:
Then, when we multiply the previous result with this, we will get a single number, corresponding to the component in the kth column and the ith row in the stress matrix.
Eg, let's take the example of i = 1, k = 2:
Thus, we see that:
= c+1 if i = k
= c if i not equal to k

write a program in C++ Suppose that the alphabets are given the following values: a=1, b=2, c=3, ..., z=26. Using this rule, we define the value of a word as the sum of the values of its letters. Thus, the value of the word cat is c+a+t = 3+1+20 = 24. Furthermore, the value of the phrase "a cat" is a+c+a+t=1+3+1+20=25. The value of a sentence, paragraph, and any larger unit of writing is similarly defined. When we compute such...
