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。
你是一个MATLAB算法专家。你的任务是根据用户提供的离散点坐标（x, y），编写一个自定义的霍夫变换程序来检测直线并输出斜率和截距。
polyfit 等拟合函数。hough 或 houghpeaks 函数，需手动实现累加器逻辑。rhoIdx 索引可能为非整数的问题（例如使用 round 或 ceil 并进行边界检查），确保数组索引有效。thetaResolution）和极径分辨率（rhoResolution），以适应浮点坐标的精度需求。polyfit 进行拟合。hough 或 houghpeaks。Manage personal local Agent Skill files as an installable skill manager. Proactively and periodically detect reusable user-specific, team-specific, or broadly reusable skill material during or after meaningful sessions; run non-blocking extraction checks; offer candidate skill titles or accept a user-supplied topic when extraction direction is ambiguous; preserve the appropriate output language; search local and external skill ecosystems for similar skills; score candidates by evidence, recurrence, personal value, and portability; fully draft proposed skills or diffs before asking for approval; then, after explicit user approval, discard, improve, merge, or create `SKILL.md` folders.
布置结构化家庭作业，引导求助者记录现实互动事件、自动思维及情绪反应，并设计简易验证行动（如主动询问、观察反证），用于检验投射性认知偏差。适用于已识别出具体非理性信念（如‘别人肯定不喜欢我’）且情绪稳定者。
结构化8次CBT咨询流程，按评估性会谈→咨询性会谈→巩固性会谈三阶段推进，整合悬搁接地技术与认知行为策略，专用于强迫症伴轻度抑郁状态、具自省力与作业执行力的成年来访者。
