Hi all,
I am trying to calculate the position of a point (x y z) with help of the points rotations. i have declared the rotation and all the other point inside the same m file. But i still get the below error
??? Undefined function or method 'In' for input arguments of type 'char'.
Thank in advance.
Regards, Bala

Please post the complete error message and show the line, which causes the error.

You aren't, by chance, trying to take the natural logarithm are you? The function for that is log().

Hi all,
thanks for the reply, but i just have the following code and i got this error. don't know why i am having this problem.
MAIN_CORD_SYS = [0 0 0];
MAIN_CORD_SYS_RELATIVE= [30 0 10];
CAB_CORD_SYS=[-165 0 785]; % The CVM uses MAIN relative
ENGINE_CORD_SYS_RELATIVE = [35 0 10];
FRONT_AXLE_CORD_SYS_RELATIVE = [304 0 100];
CAB_REF_POINT=[16.00 -37 87.00];
ENGINE_REF_POINT=[10.00 0.00 25.00];
FRONT_AXLE_REF_POINT=[80.00 0.00 0.00];
roll= (3.705866E-05)*(180/pi);
pitch=(-2.732535E-05)*(180/pi);
yaw=(-1.924688E-04)*(180/pi);
RX = [1 0 0;0 cos(roll) sin(roll);0 -sin(roll) cos(roll)];
RY = [cos(pitch) 0 -sin(pitch);0 1 0;sin(pitch) 0 cos(pitch)];
RZ = [cos(yaw) sin(yaw) 0;-sin(yaw) cos(yaw) 0 ;0 0 1];
XYZ=(RX*RY*RZ);
XZY=(RX*RZ*RY);
YXZ=(RY*RX*RZ);
YZX=(RY*RZ*RX);
ZXY=(RZ*RX*RY);
ZYX=(RZ*RY*RX);
R=XYZ;
RESULTS= MAIN_CORD_SYS_RELATIVE+(CAB_REF_POINT*R);
MR+CAB_REF_POINT;
Output=RESULTS-(MR+CAB_REF_POINT)

Please, Bali, post the complete error message. It contains the line, which causes the problem. It is not useful if we try to guess, what your problem is, when it appears explicitely written in your command window.
In addition you should use the debugger, to find out, what's going on: Type "dbstop if error" in the command window and run your program again. Then Matlab stops, when the error occurs and you can check the variables.

I don't see how you're getting the error you report with this. I can see how you get an error that MR is not defined, but nothing about "In"

Hi all,
Thanks for the help.
I found out the problem, i was having sapce in the file name "In File.m" and it caused the below error
??? Undefined function or method 'In' for input arguments of type 'char'.
The file works fine after removing the space in the file name.
once again thank you everyone.

Hi every one,
when i run this code
import ETS2.*
syms a1 a2 x y real
q1 = 30; q2 = 40;
E = Rz('q1')*Tx(a1)*Rz('q2')*Tx(a2);
TE = E.fkine( [q1,q2] );
simplify(TE)
it give error like this
''Undefined function or method 'Rz' for input arguments of type 'char'.
Error in ==> Untitled at 4
E = Rz('q1')*Tx(a1)*Rz('q2')*Tx(a2);''
please guide me.
thanks in advance

You appear to be importing java methods related to European Truck Simulator 2. Where did you find the java code?
