Fail to Convert .mat to .csv file-CodePudding

I would like to convert matlab.mat file to a .csv file. Here is the loading procedure:

>> FileData = load('matlab.mat')

FileData = 

  struct with fields:

    MIMICtable: [278340×59 table]

Then I tried to save the CSV file but the following error occurs:

>> csvwrite('file.csv',MIMICtable)
Check for missing argument or incorrect argument data type in call to function 'real'.

Error in csvwrite (line 47)
    throw(e)

I am not sure the meaning of the error message. Could someone help?

CodePudding user response：

Your data is a table object. Use the function writetable to write it to a CSV file. csvwrite accepts only numeric arrays as input.

Yes, this is a weird error message. On the other hand, csvwrite is no longer recommended, which means it has been superseded by a newer function, and is no longer maintained.
