how to write to one decimal point from matlab to excel

17 views (last 30 days)
Hello Guys,
I need to write the values to excel from matlab script with only one decimal point.
This is the code I used for exporting data to excel:
final_result = {Power;Power1;Power2;Power_percent};
if datasave==1
function UpdateSpreadsheet(final, Spreadsheet_name, Tab_name)
ReadData = xlsread(Spreadsheet_name,Tab_name);
n= Columns+2;
xlsb = mod(n-1,26)+1 ;
xmsb = fix((n-1)/26) ;
%// find MSB (recursively if necessary)
if xmsb >= 1
col = [excel_column(xmsb) char(xlsb+64)] ;
col = char(xlsb+64) ;
cellReference = sprintf('%s1', col);
xlswrite(Spreadsheet_name, final, Tab_name, cellReference);
For example;
In excel it is showing like below:
Power 113.2790977
Power1 65.85196443
Power2 80.54553664
Power_percent 92.23339083
But I need the output to be:
Power 113.2
Power1 65.8
Power2 80.5
Power_percent 92.2
Can you guys help me with this?
Thanks in advance

You could convert those numbers to strings before writing, if you don't mind rounding to one decimal place rather than truncating:
xlswrite(Spreadsheet_name, cellfun(@(x)sprintf('%.1f',x),final,'UniformOutput',false), Tab_name, cellReference);
Or you can set the cells' NumberFormat directly, along these lines:

What if you round your array with round before you send it to Excel?
array = round(array, 1);
xlswrite(filename, array);

For example I have my array as
result= [distance; speed; time; power]
when I do this it is showing me this below error, because the array is not values
ERROR: Error using round
First argument must be a numeric, logical, or char array.
So, it should read these values and round them off before exporting the values to excel.
how to do this? In my script , it is not the numbers in the array to round them off
Thanks in advance
