Use variable as placeholder in a path
显示 更早的评论
I am trying to use a variable as a placeholder in a path but I keep getting an error.
data = dlmread(['/Users/reubs/Documents/Data/PO1/' cell2mat(filenames(trialnumber))],'',1,0);
I want to rewrite this as
path1 = '/Users/reubenaddison/Documents/Data/PO1/';
data = dlmread([fullfile(path1) cell2mat(filenames(trialnumber))],'',1;0);
but I get
"Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters."

path1 = '/Users/reubenaddison/Documents/Data/PO1/';
data = dlmread(fullfile(path1, num2str(cell2mat(filenames(trialnumber)))),'',1,0);
% ^ convert num to str in fullfile ^^ use a , in place of ;

Try this:
folder = '/Users/reubenaddison/Documents/Data/PO1/';
fullFileName = fullfile(folder, filenames{trialnumber}) % Use braces!
data = dlmread(fullFileName);
See the FAQ to learn when to use parentheses, braces, and brackets:
