Question

From the following desktop view of workspace, choose the correct code.

(a) a=10;b=’pi’;syms c; d=[1,2;0;4];

(b) a=10;b=’pi’;syms c; d=[1,2;0,4];

(c) a=10;b=pi;syms (c); d=[1,2;0,4];

(d) a=10;b=’pi’;syms c; d=[1,2;0,4];

I have been asked this question in exam.

The doubt is from Managing Variables topic in portion MATLAB Basics of MATLAB

Answer 1

Correct option is (a) a=10;b=’pi’;syms c; d=[1,2;0;4];

For explanation I would say: ‘b’ is a character variable, within inverted commas. ‘a’ is a double variable. ‘c’ is a symbolic object while ‘d’ is a 2*2 matrix. The declaration of the variables is in accordance to the following code:

a=10;b=’pi’;syms c; d=[1,2;0;4];
