MATLAB: Fread + double-precision 8-byte floating point + precision

Question

Hi All,

I want to use fread to read my binary file. The data type are "double-precision 8-byte floating point". When I put 8*double as precision, it gives me weird values that I am sure it is wrong. How can I put both float + double in precision?

Thanks a lot

Farz - if the data type (within your file) is double-precision 8-byte floating point, then why not just use double or float64 as either should correspond to 8-byte floating point numbers? Check out fread input argument precision and use fread as (for example)

 A = fread(fileID,[3 3],'double');
