So, I am trying to import some text files and then write them to csv files but the importdata is not importing the entire text file.

importdata('NACA644421_test.txt')

is what I am using.

what is imported is a 1x1 struct with a 4x2 textdata cell and a 1x1 value. I made it look like code so you could see how the text file is delimited.

4x2 textdata:
'Xfoil polar. Reynolds number fixed. Mach  number fixed            '  ''
'Polar key  xf-naca644421-il-1000000-n5          '  ''
'Airfoil'  'naca644421-il'
'Reynolds number'  ''
1x1 value:
1000000
Below is the text file
Xfoil polar. Reynolds number fixed. Mach  number fixed            
Polar key  xf-naca644421-il-1000000-n5          
Airfoil  naca644421-il          
Reynolds number  1000000          
Ncrit  5          
Mach  0
