MATLAB M文件的编码规范对于确保代码的可读性、可维护性和一致性非常重要。下面是一份MATLAB M语言编码规范的建议,可以作为参考:
my_function_name.m
)。开头文档块:每个M文件开始处都应该有一个描述性的注释块,包括函数用途、输入输出参数说明、作者、日期等。见下方实例
内联注释:在复杂的代码段前或后添加注释,解释其目的或逻辑。
持续更新注释:当修改代码时,相应更新注释。
%MY_FUNCTION_NAME Example function to demonstrate the use of an H1 line and help text. %MY_FUNCTION_NAME(X) takes input X and returns the result of some operation. % % Input: % X - A numeric vector or matrix % % Output: % Y - The output vector or matrix after applying the operation % % Example usage: % Y = my_function_name([1 2 3; 4 5 6]); % % Author: Vincent % Date: July 24, 2024 % Version: 1.0 function Y = my_function_name(X) % Function body starts here...

function dotProduct = safeDotProduct(v1, v2) % SAFE_DOTPRODUCT Computes the dot product of two vectors safely. % DOTPRODUCT = SAFE_DOTPRODUCT(V1, V2) computes the dot product of two % vectors V1 and V2. If the vectors do not have the same length, it throws % an error. % % Input: % v1 - First vector (numeric array) % v2 - Second vector (numeric array) % % Output: % dotProduct - Dot product of the vectors (numeric scalar) try if ~isequal(size(v1), size(v2)) error('Vectors must have the same length.'); end dotProduct = dot(v1, v2); catch ME fprintf('Error: %s\n', ME.message); dotProduct = NaN; % 或者可以返回一个特定的错误代码 end end
sumSquares = 0;
for i = 1:length(v)
sumSquares = sumSquares + v(i)^2; % Not recommended
end
sumSquares = sum(v.^2); % Recommended
% 预分配数组
n = 1000000; % 数组最终大小
A = zeros(1, n); % 预分配数组
for i = 1:n
A(i) = i; % 直接赋值,无需重新分配内存
end
不推荐方式
% 不预分配数组
n = 1000000; % 数组最终大小
A = zeros(1, 0); % 初始化为空数组
for i = 1:n
A(end+1) = i; % 每次迭代增加一个元素
end
function print_results(a, b, c)
% PRINT_RESULTS Prints results with formatted output.
% PRINT_RESULTS(A, B, C) prints the values of A, B, and C in a specific format.
%
% Input:
% a - First value (numeric scalar)
% b - Second value (numeric scalar)
% c - Third value (numeric scalar)
fprintf('The values are: A = %.2f, B = %.2f, C = %.2f\n', a, b, c);
end
遵循这些规范将使您的代码更加专业和易于管理。当然,这些规范可能需要根据具体项目需求进行适当调整。
