Hellow, i'm using textscan to extract info out of an ascii file. My ascii file has a precision of six numbers after the point. But when i use my program, the numbers convert to a four digit number. my code is:
while (~feof(fid)) % For each block...
InputText=textscan(fid,'%s',1,'delimiter','\n'); % Read header line
HeaderLines{Block,1}=InputText{1};
disp(HeaderLines{Block});
NumCols= nd;
FormatString=repmat('%f',1,NumCols); % Create format string based on parameter
InputText=textscan(fid,FormatString,'delimiter','slice'); % Read data block
Data{Block,1}=cell2mat(InputText); % Convert to numerical array from cell
[NumRows,NumCols]=size(Data{Block}); % Size of table
disp(cellstr([xlate('Table data size: ') num2str(NumRows) ' x ' num2str(NumCols)]));
disp(' '); % New line
Block = Block+1; % Increment block index
end
now when i use InputText=textscan(fid,'%f','delimiter','slice'); the resolution of my matrix isnt right anymore... Thx

The program does not convert to four digits accuracy: you have set Matlab to only display 4 digits by default.
Give the command
format g long
and then display the matrix.
