I have the code to plot a line of best fit through my data but now I am trying to do this for multiple data sets in a for loop but it gives me errors that the vectors must be the same length. I know my indexing is wrong somewhere but I cant work out where.
I want it to loop through each column of my 7x2 matrix, and calculate the line of best fit for each column, and tell me the gradient and angle of the line.
p = polyfit(x(a),y(a),1);
angle(a) = rad2deg(atan(p(1)));
Vectors must be the same length.
