prompt for variables in an equation
显示 更早的评论
Hello,
I am new here and to Matlab so here is my question. How do I promp a user for variables in an equation and after the answer is given to loop back again in order to enter new variable?
example:
promp for r
promp for h
r^2*acos((r-h)/r)-(r-h) * sqrt(2*r*h-h^2)
answer =
Loop

while true
r = input('How about sending an r value over this way?');
h = input('Groovy. Got a spare h value too?');
r^2*acos((r-h)/r)-(r-h) * sqrt(2*r*h-h^2)
end

How do you break the loop when you get an answer?

while true
r = input('How about sending an r value over this way?');
if isscalar(r) && isnumeric(r); break; end
end
while true
h = input('Groovy. Got a spare h value too?');
if isscalar(h) && isnumeric(h); break; end
end
disp( r^2*acos((r-h)/r)-(r-h) * sqrt(2*r*h-h^2) )

Hi Ken,
i think the instruction input is what you need.
ex.
reply = input('Do you want more? Y/N [Y]: ', 's');
if isempty(reply)
reply = 'Y';
end

At the point you have written "promp for r" and "promp for h"
