i am using the new mathscript structure feature for data in labview 2011. i have several .mat files created in a binary format comprised of a complex data structure (called PFFT) that entails sampled time data, their FFTs and several sampling parameters. this data structure is much too large and complex to flatten into individual files. Instead, signal analysis proceeds by processing various arrays via matlab, or labview, within the data structure and updating it.
what i like in the recent LV 2011 support of structures in mathscript is that i can load the original .mat structure quite nicely as a simple load(file). Also the parameters/complex arrays are accessible using the same structured data format as in matlab.
my problem is that i want to modify existing elements of the data structure and save it in its entirety to the same file. my limited understanding of matlab/mathscript is to use a save(file) or save (file, 'PFFT") command. However, when i do this the original .mat file is not updated, but is rewritten with a .mat.bak extension. In addition the .mat file that contained the PFFT structure is rewritten and empty without any variables added. I am not a matlab programmer and am trying to avoid processing in matlab. However, at this point i do not know if my difficulty stems from not knowing the proper syntax, or whether its a shortcoming in saving mathscript structures.
thanks in advance
