loading mat file problem
in [Matlab]

From: nurul on 24 Jul 2010 01:13 hi everyone.. im new in gui matlab.. i got problem in loading the .mat file. there are several .mat file that being needed for the calculation which it contains data. and the function to calculate n compare the file class is like this. .. .. .. testlogliknpVSp=mhmm_logprob(b(:,:),priornp,transmatnp,munp,Sigmanp,mixmatnp);%NOPAIN MODEL testloglikpVSp=mhmm_logprob(b(:,:),priorp,transmatp,mup,Sigmap,mixmatp); %PAIN MODEL if testloglikpVSp > testlogliknpVSp .. .. .. all the priornp, priorp, transmatnp,transmatp, etc need to read all the .mat file. --->so the question is, how do i load the .mat file(there are 12 files) so that priornp,transmatnp,munp,Sigmanp,mixmatnp,etc can work fine and read the data? i dont want to use uigetfile to load all the 12 .mat files. and my previous load codes didnt work. please someone help me. any kind help is so much appreciated

This code is not meaningful for the readers. > --->so the question is, how do i load the .mat file(there are 12 files) > so that priornp,transmatnp,munp,Sigmanp,mixmatnp,etc can work fine and read the data? i dont want to use uigetfile to load all the 12 .mat files. and my previous load codes didnt work. please someone help me. If you previous load codes didn't work, post them together with a description of the errors (e.g. error message or difference between expectations and results). "Didn't work" and the rest of your post does not contain enough (any) information, which could help us to solve your problem. In general: Load MAT files with the LOAD command. S1 = load(FileName1); S2 = load(FileName2); ... etc Then access the variables of the Mat-files as fields of the structs S1, S2, ... Kind regards, Jan
From: nurul on 25 Jul 2010 20:25 thank you so much jan.. can i ask, one more thing? by right, i have loaded the mat files, its working and read the variables in the workspace. and i have an input(wav file) to be verified, therefore , i assign it to the function to execute the calculation. but then, it says the input is not a scalar. therefore, i make the variable as a scalar, and it says matrix dimension must agree. any idea why does this happening?

It sounds as if you might be passing the file *name* instead of the _content_ of the file.

owh. hehe. how do i pass the content? i use evalin. so it means it didnt work(but when i test, it seems to reading). can u give me rough idea on the codes how to pass the variable/content please? thank you.. |
