在Matlab中创建嵌套单元格数组？
 

我有两个单元格数组，一个叫做info {}，另一个叫做data {}。我正在从一个文本文件中读取信息，并将这些行放入info {}单元格数组中。当程序找到空行时，我想从一个新的info {}单元格数组开始，并继续插入行，直到找到另一个空行为止。

global data global tags tags{} data = {}; line = fgets(fid); counter = 1; while ischar(line) if regexp(line,'/locus_tag=','match','once') tags{end+1} = line; else info{counter} = line; if strcmp(newline, line) data{end+1} = info; info{counter+1}{end+1} = line; end end line = fgets(fid); 结束

我已经包含了一些无效的代码，但这是到目前为止的结果，我想我知道我需要使用算法来执行此操作，但是在实现时遇到了一些麻烦。有任何想法吗？

最后我想要的东西看起来像

data = { {info1} {info2} {info3}... {infon}

我认为类似的事情会起作用，尽管没有示例数据文件我无法确定：

%# Load all the lines from the file: allLines = {}; %# An empty cell array to store all lines in the file fid = fopen('data.txt'); %# Open the file nextLine = fgetl(fid); %# Get the next line while ischar(nextLine) %# Check for an end-of-file condition allLines = [allLines; {nextLine}]; %# Add the line to allLines nextLine = fgetl(fid); %# Get the next line end fclose(fid); %# Close the file %# Remove any trailing whitespace from the lines: allLines = deblank(allLines); %# Find tags and remove them: index = regexp(allLines,'/locus_tag=','once'); %# Index of matches index = ~cellfun(@isempty,index); %# Find where index isn't empty tags = allLines(index); %# Get cells with tags in them allLines(index) = []; %# Remove cells with tags %# Find empty lines and group non-empty spans into cells: index = cellfun(@isempty,allLines); %# Find empty lines allLines(index) = []; %# Remove cells with empty lines counts = diff([0; find(index); numel(index)+1]); %# Get the number of lines counts = counts(counts > 1)-1; %# to put in each group data = mat2cell(allLines,counts); %# Group the non-empty lines 上面使用的一些功能： [URL="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/fgetl.html"]FGETL[/URL] ， [URL="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/deblank.html"]DEBLANK[/URL] ， [URL="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/regexpi.html"]REGEXP[/URL] ， [URL="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/cellfun.html"]CELLFUN[/URL] ， [URL="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/mat2cell.html"]MAT2CELL[/URL] 。
