IsfRead

A function that read the binary files in .isf format generated by Tektronix MSO4000 series oscilloscopes.

Example useage:

filename = 'TEK0000CH1.ISF';
[data, header] = isfread (filename);
plot(data.x,data.y)

I looked isfread.m uploaded by John Lipp (File ID: #6247) and made some changes.
(1) it is able to read isf files generated by MSO4000 series;
(2) the header length is variable;
(3) it is possible that the command sequence in header is not fixed;
(4) not all parameters in header are necessary to read;

I tested this function only on isf files generated by a MSO4054 oscilloscope. For other series and models, you may have to read the programmer's manual and make some modification.
