Problem with Excel Open method

Question

0 个投票

Hi,

I am trying to use MATLAB to export some data. I implemented the following code snippet and plan to use the xlswrite1 function after (there is a lot of data to transfer):

function [] = write_out_dl21(fullfilename_in,dl21_param,data_in_display,data_in_summary_itvl,data_in_summary_total)
% Open file and call Excel methods
[pathstr, filename_in, file_ext] = fileparts(fullfilename_in)
% Excel methods DO not like spaces in the file names!
filename_in=strrep(filename_in,' ','_')
fullname_out = strcat(pathstr,'\',filename_in,'_OUT',file_ext);

The code above gives the error:

??? Invoke Error, Dispatch Exception:
Source: Microsoft Excel
Description: Excel cannot open the file 'inner_oslofjord_1_udp_ALL_EN_OUT.xlsx' because the file format or file
extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of
the file.
