In the help documation of fread function,there are senven kinds of datatypes which are listed below. single 32 (4) double 64 (8) float 32 (4) float32 32 (4) float64 64 (8) real*4 32 (4) real*8 64 (8)
And the result value is the same when i use "single" and "float32" and that the datatype is not single or float32 but double.IS it right?If right,what's the difference in single and float when reading data with fread function.
The matlab code is pasted below. fp = fopen(strCombineOutputFile); if(fp == -1) errordlg('File not found','File Error'); return; end for i=1:1320 OutputCombineSlice1{i} = fread(fp,[720,2],'single'); %OutputCombineSlice1{i} = fread(fp,[720,2],'float32'); end

fread has a habit of reading the correct data type, but returning it as a double.
float and single should be identical.
