I have been sent data file with a .cdf extension. It is supposed to contain time and light absorbance data. When I use the cdfread('Filename.cdf'), I get an error message in Matlab 2019b

"The file format is netCDF, not CDF. See "help netcdf"

From the NetCDF documentation, https://www.mathworks.com/help/matlab/network-common-data-form.html,

if ncdisplay is used then I get the error message

"Error using ncdisp

Too many output arguments."

Lastly, I tried ncinfo, and then the output is 1x1 structure. How should one proceed to extract numerical data from this file in Matlab? I have tried using PeakFit to open it and save the data as .dat file and then proceed with it, however, it would be better open directly in Matlab.

P.S. I had also tried Import Data, and the output was garbled characters. Thanks
