Hellow, i'm reading in data from an ascii file. And i get it with

Inputpara = textscan(fid,'%s',14,'delimiter','\n'); % Read strings delimited 
Meapara = Inputpara{1};
Mvalues = cellfun(@(x)sscanf(x,'%f'),Meapara(5:end))

And now i can get the number out of Mvalues! But there are also string in it i want to use. Meapara exist of several strings like 'Stringvalue // value of string' Now i want to extract everything before the // . So i want a STRING! I tried everything but always error... that it is a cell and not a string... Please help me :)

在 MATLAB Online 中打开

strings = regexp(Meapara,'^(.*?)//', 'tokens');

strings will now be a cell array of the parts before the // -- including any spacing (since you did say you want to extract everything before the //).
