MATLAB: Help with matlab, dimensions of matrices being concatenated are not consistent, why

concatenatedconsistentdimensions

I keep getting this error, Dimensions of matrices being concatenated are not consistent.
Here's my code:
 x = [0.00, 100.00, 200.00];
 y1 = [100.00, 138.50, 175.83];
 y2 = [(175.83/200) * x];
 y3 = [(y1) / x];
 [hAx,hLine1,hLine2] = plotyy(x,y1,[x',x'],[y2',y3']);

Best Answer

Seeing what you are trying to do in the call to plot, I suspect that you didn't want to solve a linear system when you defined y3, but wanted instead an element-wise division?
 y3 = y1 ./ x ;
