'Polyfit issue with vector sizes even though size() function shows they're the same
I am receiving this error message, but I've printed the size of my two vectors and they're identical. I'm not sure what else could be causing it

Solution 1:[1]
The third argument to polyfit should be a number indicating the degree of the polynomial. You've given it a string, which is confusing it. If you want a linear fit, use polyfit(x, y, 1).
