Mworks清除命令

MWorks 中清除命令的使用方法
在 MWorks 或类似的 MATLAB 类环境中，clear 命令用于管理当前工作区内的变量和其他对象。这有助于减少内存占用并防止不同脚本之间的干扰[^1]。
clear 的基本语法
最简单的形式是不带参数调用 clear：
clear

此命令会移除工作区内所有的变量。
如果希望仅删除特定名称的变量，则可以在 clear 后面指定这些变量的名字：
clear varName1 varName2
登录后复制
这里 varName1, varName2 是要被清理的具体变量名。
有时可能想要清除非全局作用域内定义的所有局部变量，在这种情况下可以使用 -all 参数来实现更彻底的清理过程：
clear all
登录后复制
上述指令不仅会清除所有普通变量还会连同函数句柄、关闭图形窗口以及重置随机数生成器的状态等。
为了确保每次运行程序之前都处于一个完全空白的工作环境之中，建议养成习惯于每段新代码开头处加入适当类型的 clear 调用来初始化状态。

MWorks TOPSIS Implementation and Usage in Multi-Criteria Decision-Making
TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is a widely used method for multi-criteria decision analysis. In the context of MWorks, this technique can be implemented effectively to evaluate multiple alternatives based on various criteria.
Overview of TOPSIS Methodology
The core idea behind TOPSIS involves determining an ideal solution and an anti-ideal solution from given data points. The optimal choice will have the shortest distance to the ideal solution while being farthest away from the anti-ideal one. This approach ensures that decisions are made considering both positive and negative aspects simultaneously[^1].
Steps Involved in Implementing TOPSIS within MWorks Environment
To implement TOPSIS using MWorks:

Data Normalization: Normalize all criterion values so they fall into comparable ranges.
Weight Assignment: Assign weights reflecting relative importance among different criteria.
Ideal Solutions Calculation: Compute weighted normalized matrices to derive positive and negative ideal solutions.
Distance Measurement: Calculate Euclidean distances between each alternative and these two reference points.
Closeness Coefficient Computation: Determine closeness coefficients indicating how close each option lies towards the best possible outcome compared with worst-case scenarios.
Rank Ordering Alternatives Based On Closeness Coefficients

Below shows Python code snippet demonstrating basic steps involved when applying TOPSIS algorithm inside MWorks environment:
import numpy as np

def topsis(data_matrix, weight_vector):
# Step 1 & 2: Data normalization followed by weighting assignment
norm_data = data_matrix / np.sqrt((data_matrix**2).sum(axis=0))
w_norm_data = norm_data * weight_vector

# Step 3: Find out Positive Ideal Solution(PIS) and Negative Ideal Solution(NIS)
pis = w_norm_data.max(axis=0)
nis = w_norm_data.min(axis=0)

# Step 4: Distance calculation
d_pos = ((w_norm_data - pis)**2).sum(axis=1)**(1/2)
d_neg = ((w_norm_data - nis)**2).sum(axis=1)**(1/2)

# Step 5: Relative closeness computation
cc = d_neg/(d_pos+d_neg)

return cc

This function takes input parameters including data_matrix representing performance metrics across options under evaluation along with corresponding weight_vector. It returns relative closeness scores which help rank order potential choices objectively according to their proximity toward desired outcomes versus undesired ones[^3].

mworks curve

关于 MWORKS 中 Curve 功能的实现与用法
尽管当前提供的引用资料并未直接提及 Curve 功能的具体细节，但从已知的信息可以推测其可能的应用场景和技术背景。
1. 曲线拟合与数据处理
MWORKS 是一款用于科学计算和工程仿真的工具，在 MATLAB 替代方案中具有一定的潜力。对于曲线相关的功能，通常涉及以下几个方面：

数据可视化在图形视图下可以直接查看传递函数模型[^1]，因此类似的机制也可能适用于其他类型的数学表达式或实验数据。通过内置绘图模块，用户能够绘制并分析各种形式的数据分布曲线。

数值方法支持借助类似于 MATLAB 的插值算法、最小二乘法或其他优化技术，MWORKS 可能提供了对离散点集进行平滑化处理的能力。这种能力有助于构建连续型曲线表示形式。

2. 编程接口调用
为了更好地利用这些特性，开发者可以通过编写自定义脚本来扩展系统的原生功能。然而需要注意的是，相较于成熟的商业产品而言，该平台尚存在诸多局限之处[^2][^3]:

如果尝试采用 Julia 编程语言，则需克服性能瓶颈以及兼容性挑战；
对于传统 .m 脚本的支持情况也存在一定差异——某些特定语法结构或许得不到完全解析执行；

以下是假设性的 Python 风格伪代码片段演示如何操作此类对象：
import mworks as mw

# 创建一个新的工作空间实例
workspace = mw.Workspace()

# 加载外部 CSV 数据源作为输入参数集合
data_points = workspace.load_csv('example_data.csv')

# 应用多项式回归得到最佳匹配路径描述符
fitted_curve = data_points.fit(order=3)

# 将结果导出至独立文件保存以便后续查阅验证
fitted_curve.save_to_file('output_model.json')
