A = [1 1 0 0]
B = [1 ;2 ;3 ;4]
C=A*B

syms x;limit(((1-cos(x))/(x^2)),x,Inf)

 syms ‘x’ makes the declaration long-lasting 

 MAT files are Binary files created by MATLAB 

x=sin(10);y=pi;whos

  How can we close all graphs in MATLAB 

 What is the condition on x in bar(x,y) 

 How will one escape from printing graphs of variables, whose value gets changed for the program 

Consider the following MATLAB code:

A = [true false true; true true false]
A = 1     0     1
   1     1     0
B = cumprod(A,2)

If the 'solve' function does not return any solution, what does it imply?
