Use matlab or another software program to calculate the following. a. let a=[.1.2.3.4; .4.3.2.1; .3.1.4.2; .2.4.1.3]. find a^1.b. let b=[.1.2.3.4; .4.3.2.1; .3.1.4.2; .2.4.1.29]. find b^1.c. let c=[.1.2.3.4; .4.3.2.1; .3.1.4.2; .2.4.1.31]. find c^1.d. comment on the differences between a, b and c. what is the sum of the entries in each row of a, b and c? what is the sum of the entries in each column of a, b and c? e. comment on the differences between a^1, b^1, and c^1. how large are the entries of each? draw analogies to 1^1 for a and .91 for b and 1.11 for c
