Read Microsoft Excel spreadsheet file. The xlsread ignores leading rows or columns of text. However, if a cell not in a leading row or column is empty or contains text, xlsread puts a NaN in its place in the return array, num.
One reason this may occur is if some other application has established an ActiveX connection to Excel and is hanging on to a reference to the interface, and not releasing it.
The way ActiveX works is that if 2 applications both make connections to the same server, the server will not close until both applications have terminated their connection.
If you are experiencing this same issue with a later version of MATLAB, or do not have Google Desktop Installed, there is likely another application on your computer which is holding on to the Excel application ActiveX reference. One way to work around this issue is to identify the application that is causing this issue, then disable it.
You can also contact the company which created the software to notify them of this issue. Certain Excel add-ins may also prevent proper termination of Excel. Disabling the add-ins that cause issues is a possible workaround. When you use a Bloomberg add-in, that causes this issues: Please open a help chat by pressing the help key twice on the Bloomberg keyboard and ask for the technical departement.
Bloomberg will then have a look into these issues.Append new columns into Excel with MATLAB. Learn more about matlab, excel, column, append, add new columns.
MS Excel and Matlab (interchanging data) In this article we'll show how to interchange information between MS Excel and Mathworks' Matlab, working from a Matlab m-file. There are two handy Matlab instructions for this purpose: xlsread and xlswrite. This function writes a cell array into a CSV-file.
It works with empty cells, numeric cells, char cells, and string cells.
One array can contain all of them. I am storing the values related to these variables in a excel file using xlswrite. When i run the matlab program second time, the output data related to the another input file that I have selected should be stored in the same excel file at different locations.
How to append data to current row in an excel Learn more about matlab, vector, excel. Use xlswrite function.
However in case you are not using windows system, this may be a problem. Alternative, use csvwrite or any other way to save data as comma delimited file and open it in Excel. MATLAB has an entire help section devoted to I/O specific to excel. You can read about those here in.
