Question

3) You are given a 2D array as follows: 1 35 A=24 L7 9 2 Use MATLAB to find the following (i.e., write an appropriate MATLAB statement for each): (a) What is the c (b) What is the row mean of A? (c) What is the mean of the entire array A? (d) What is the column standard deviation of A? (e) What is the row standard deviation of A? olumn mean of A? (f) What is the entire array's std. deviation? (g) What is the column minimum of A? (h) What is the row minimum of A? (i) What is the column maximum of A? What is the row maximum of A?

Explanation / Answer

a)

b)

c)

Mean = mean(A)

d)

RowSTD = std2(A,1)

e)

ColumnSTD = std2(A,2)

f)

STD = std2(A)

g)

ColumnMin = min(A,1)

h)

RowMin = min(A,2)

i)

CoulmnMax = min(A,1)

j)

RowMax = max(A,2)
