MATLAB has many string array functions that return logical arrays, such ascontains,startsWith, andmatches. You can use these to operate on text using logical indexing. For example, you could extract all the space program names containing “Skylab.” >> names names = 6×1 string array "Mercur...
The data is formatted in columns containing fields such as: {ID (string), date (string), numeric data, flag (string), ...}. I get the data as a cell array, with each cell having a column of data. What I've done is cast everything into a string and take the transpose of the ...
% Question : How do I get the sorted matrix as a 5X1 matrix now? Required sorted output matrix : s =["1 9:53.334" "2 2:45.623" "3 9:23.545" "4 12:01.213" "5 2:16.245"] Suggestions, if any, for better/more effficient ways to this string data are welcome. ...

string array变量加载进来为None; 这个问题,目前没有啥好的解决方案只能选用char方法生成列名数组。 h5py 使用h5py.File的方式我们可以正常解析mat7.3文件,变量访问方式与字典比较类似,但不是字典。存在的问题: char array数组被转换成ascii的形式,数据类型(dtype)为unit*,需要转换才能得到原始信息; ...

创始: MATLAB(Matrix Laboratory 的缩写)最初是在1970年代末由Cleve Moler开发的,他当时是新墨西哥大学的计算机科学教授。Moler 开发 MATLAB 主要是为了让他的学生们更容易地访问LINPACK和EISPACK项目而不必学习Fortran语言,这两个项目都是进行矩阵计算的数学软件包。它迅速在应用数学和工程领域中变得流行起来。
