Undefined function 'curveintersect' for input arguments of type 'double'.

3 visualizaciones (últimos 30 días)
I have two non-linear sets of data A & B which I have plotted against specific variable(K) on the same graph. Neither A nor B have a common data point at which they intersect, however, when their dots are connected and they are graphed, the lines do intersect. Is there a command to calculate the values at this point? when I use curveintersect function, Undefined function 'curveintersect' for input arguments of type 'double'.

curveintersect is not a built-in function in MATLAB, so you cannot use it unless you have made a function file yourself.
Perhaps this would help:
Alternatively, you can use interpolating (interp1) functions and see where they intersect.
