Excel functions not auto updating
Here is a sample code: This creates a server for Microsoft Excel in MATLAB, opens the file and gets the required sheet in the workbook, reads the data, saves the file and then closes it.This might enable you to get the updated data from the sheet without having to manually open it. -Shruti Hello Shruti, Thanks for your very detailed response.Table 3.4 summarizes the operators you can use in reference formulas.I use the TODAY() function in an excel worksheet which is accessed using MATLAB (i.e. Now I have to open the excel file just to update the TODAY() function, and this method is a bottleneck in my workflow. EDIT: I'm using MATLAB's built in 'xlsread' command Hi Chris, I understand that you want to get an updated date into MATLAB without having to manually open the Excel Sheet.→ Comparison formulas also make use of Excel’s logical functions, so see “Adding Intelligence with Logical Functions,” p. The two types of formulas that I discussed in the previous sections, arithmetic formulas and comparison formulas, calculate or make comparisons and return values. Text formulas use the ampersand (&) operator to work with text cells, text strings enclosed in quotation marks, and text function results.
Most of the time, you will search on the Internet for some advice.Table 3.2 summarizes the mathematical operators used in arithmetic formulas. For example, you can determine whether to pay a salesperson a bonus by using a comparison formula to compare actual sales with a predetermined quota.If the sales are greater than the quota, the rep is awarded the bonus. For example, if the amount a customer owes is more than 150 days past due, you might send the invoice to a collection agency.I know it's possible to set Excel to automatically update cells upon being opened under the calculation tab, but apparently this does not apply to MATLAB (or COM interfaces in general? I tried this with the “Now” function in Excel, and I could see the updated values using “xlsread” so I’m not sure if I have misunderstood your question.Alternatively, you could try the below method to read data from Excel: Since opening the sheet manually updates it, but “xlsread” in MATLAB doesn’t, I tried to use the “actxserver” in MATLAB to achieve a similar effect.
