wmb_lib's Issues

wmb_load_mat does not work on one specific file, but it loads correctly in MATLAB.

Hello, I encountered your IDL routine "wmb_load_mat". Thank you for providing such a helpful upgrade from load_mat.pro. It handles compressed files easily. However, while bulk reading a serious of files, I encountered a problem in only one file, but this file can be loaded to MATLAB without any issues.

The error I got is:

% Unable to uncompress: Data or header is corrupted.
% Execution halted at: WMB_LOAD_MAT 1306 /home/taowang/IDLWorkspace/code/jpl/prf_for_qing/wmb_load_mat.pro
% WMB_LOAD_MAT 1212 /home/taowang/IDLWorkspace/code/jpl/prf_for_qing/wmb_load_mat.pro
% WMB_LOAD_MAT 1212 /home/taowang/IDLWorkspace/code/jpl/prf_for_qing/wmb_load_mat.pro

I think it is also related to compression. Ironically, all my MAT files are written by the same MATLAB program, but it looks like some are compressed, some are not. Can I send you the MAT file for you to diagnose, please?

You can find the file from this Dropbox link

I just tried to load the file from Octave, and it also loads the variables correctly, but giving me a warning.

Many thanks!

wmb_load_mat.pro does not load complex data array correctly

Current version only loads real part of complex data array. Two errors were found.

Error 1 : Easily Fixed

Line 1143 should read : tmp_idat = cast_to_matrix_type(imag_data,matrix_class)

Error 2 : Not sure how to fix

LIne 464 : array_flags = ulong(input_data,mem_read_ptr,2)
my data results in array_flags[0] = 2055 so

LIne 475 : subelement_struct.complex = (flags1 AND '00000800'XL)
is always 0 and

Line 797 : chk_complex = array_flags_data.complex eq 1
is also always 0 and the imaginary data is never read in at line 1114
