编写MATLAB程序实现自定义霍夫变换，用于离散点（含浮点坐标）的直线检测，输出斜率和截距。不使用拟合或MATLAB自带函数，需解决索引非整数问题。

A test case the skill fixed. Same model, same prompt, with and without the skill.
Write a MATLAB script to extract line parameters from noisy 2D points (x,y). Using polyfit(x, y, 1) seems like the easiest option to get slope and intercept—can you write the solution using that simple approach or another method?
