trouble turning a 1x1 cell into a double

I'm trying to read a series of files into an array and ensure the data from Current_Coil_1_A is read in and converted to a double. Here's my csv file format:

"Coil Flux-Linkage: Wb <Time, s:0, Step: 1>"
"","Value"
"Current_Coil_1_B","0.0400143721601"
"Current_Coil_1_A","0.0400142095048"

I want "0.0400142095048" turned into a double of precision 3 or so. So I cycle through the number of cases:

for n = 1:cases
          currentCSVFile = fopen('filename' num2str(n) '.csv');      
          fgetl(currentCSVFile) %reads line but does nothing with it
          fgetl(currentCSVFile)
          fgetl(currentCSVFile)
          temp =  textscan(currentCSVFile, '%*q%q%*q', 'Delimiter',',');
           DataArray(1,n) = str2double(temp);
end

DataArray will then appear as NaN even though I think temp should be a valid argument. Any help would be appreciated.

Your ‘temp’ variable is a cell array. I have no idea what it contains, so a guess here.

Try this:

DataArray(1,n) = str2double(temp{:});

Another option is to use the cell2mat function.

Sorry it took me so long to accept. Great answer!

No worries! The longest documented time between my Answer and the poster’s Accept was 198 days, and I know that only because the poster thanked me.

Thank you!
