MATLAB: User defined variable input

user

If i have sample formula k=aX1*aX2*aX3*……*aXn. here X1,X2,…Xn are vector of X=[X1 X2 … Xn]… if user input has only 2 component X1,X2 the output will be k=aX1*aX2. if user has n component in the vector then the output will be k=aX1*aX2*aX3*……*aXn. how to solve such a case

Get the user input of X using input function. Then get the length of X using length function.

Run a for loop on length of X and multiply with 'a'.

x3=x1+x2/2;

is wrong. It does not take the value half-way between the two. It can get stuck. Consider that if x1 = 1 and x2 = 2, then 1 + (2/2) = 1+1 = 2, so your x3 would be the same as your x2 and you would get stuck in an infinite loop.

set(ax1,'XColor','r','YColor','r')
ax2 = axes('Position',get(ax1,'Position'),'XAxisLocation','top',...
