please help in for loop :(

for  m=1:2
  rx=1+2*l*sin(m*b)*m 
  ry=1+2*l*cos(m*b)*m;
end
plot([1 rx 10],[1 ry 10]);

where l is given I need two value for rx and also for ry I mean that the result should be like this :

rx=0+2*l*sin(1*b)*1
ry=0+2*l*cos(1*b)*1;
rx=0+2*l*sin(2*b)*2 
ry=0+2*l*cos(2*b)*2;

Huh? Totally unclear as to what you are trying to do.

It's not clear if the first term should be 0, like after the loop, or 1, like you have it inside the loop. My answer below assumes 1.

Answer 1

Get rid of the for loop. Just do this:

m=1:2
rx=1+2*l*sin(m*b)*m 
ry=1+2*l*cos(m*b)*m;

[Mech]

ok bro, just try it. it dosent work :(

[Roger Stafford]

Image Analyst needs a 'dot':

 m=1:2
 rx=1+2*l*sin(m*b).*m; 
 ry=1+2*l*cos(m*b).*m;
 plot([1 rx 10],[1 ry 10])

However, you should be able to figure that out, Mech.

thanks alot roger its work but what th meaning of dot in this place m is matrix, by adding dot what happen ?

[Image Analyst]

It means element by element multiplication, instead of a matrix multiplication.

thank you Analyst ;)
