You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: parse.m
    path of file: ./repos/Matlab-Machine/007_Optimize data regression prediction of BP neural network based on genetic algorithm/goat
    
    the code of the file until where you have to start completion: function x = parse(inStr)

% parse 是一个函数，它接收一个由空格分隔的文本组成的字符串向量，
% 并将各个字符串项解析为一个 n 项矩阵，每个字符串一行。

% x     - the return matrix of strings
% inStr - the blank separated string vector

%%  切割字符串
strLen = size(inStr, 2);
x = blanks(strLen);
wordCount = 1;
last = 0;
for i = 1 : strLen

    
function x = parse(inStr)
