Hi, I am trying to build a Matlab function which has input parameter as arrays. This function calculate the slope and intercept of a line through 2 point. I use an array of 2 element (x,y) for a point. This is my function:
function [slope,intercept]=analyzeLine(point1,point2)
if(point1(1)==point2(1))
slope=pi/2;
intercept=0;
else
slope=(point1(2)-point2(2))/(point1(1)-point2(1));
intercept=(point1(1)*point2(2)-point1(2)*point2(1))/
(point1(1)-point2(1));
end
But when I compile the error says:
Index expression out of bounds. Attempted to access element 2. The valid range is 1-1.
Please let me know what I did wrong and what should I do.
Thank you so much! Best regards, Thang

How exactly are you calling the routine? Could you give a specific numeric example?

I have never seen that error message before. How are you calling the function?
BTW, what version of MATLAB are you using?
