100Cr6.csv

在 MATLAB Online 中打开

Hello,

I am having problem reading in this file to matlab.

Data = fileread('100Cr6.csv');
Data = strrep(Data, ',', '.');
FID = fopen('kf100CR6.m', 'w');
fwrite(FID, Data, 'char');
fclose(FID);

i use the following code but it does not generate the data what i want?

i want every data in double notation (like 1231.2354) format. so that i can use these as columns or rows of matrix.

Does anyone have a solution to this?

Many thanks.

try readmatrix() or readtable() instead

Data = readmatrix('100Cr6.csv','NumHeaderlines',1,'DecimalSeparator',',');

Data = readtable('100Cr6.csv','NumHeaderlines',0,'DecimalSeparator',',');
% FID = fopen('kf100CR6.m', 'w');
fid = fopen('kf100CR6.m', 'wt'); % Open m-file for writing as a text file.
if fid ~= -1
    [rows, columns] = size(Data)
    fprintf(fid, '', Data)
    fclose(fid)
