Read Matlab matrix into Python -



Read Matlab matrix into Python -

when i'm trying read matlab matrix python, next error

>>> scipy.io.loadmat("dynamical.mat") traceback (most recent phone call last): file "<stdin>", line 1, in <module> file "/usr/lib/python2.7/dist-packages/scipy/io/matlab/mio.py", line 151, in loadmat mr = mat_reader_factory(file_name, appendmat, **kwargs) file "/usr/lib/python2.7/dist-packages/scipy/io/matlab/mio.py", line 105, in mat_reader_factory mjv, mnv = get_matfile_version(byte_stream) file "/usr/lib/python2.7/dist-packages/scipy/io/matlab/miobase.py", line 221, in get_matfile_version % ret) valueerror: unknown mat file type, version 46, 48

the dynamical.mat file containing matrix

% size = 30 30 % nonzeros = 252 zzz = zeros(252,3); zzz = [ 1 1 1.4019896354966477e+01 1 2 0.0000000000000000e+00 1 3 0.0000000000000000e+00 ...

this question seems inactive while, allow 1 alternative in case still need read .mat file, assuming in format specified:

def read_mat( file_path ): import numpy np mat = open(file_path, 'r') mat.next() # % size = 30 30 length = int(mat.next().split()[-1]) mat.next() # zzz = zeros(18,3) mat.next() # zzz = [ ans = np.array([ map(float, mat.next().split()) in xrange(length) ]) mat.close() homecoming ans

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...

javascript - mongodb won't find my schema method in nested container - i trying access method of schema stored within mixed container. here situation : have cases model can many different things, have schema each of these things stored in "casecontent" mixed property. var caseschema = mongoose.schema({ casecontent : {}, object : {type:string, default : "null"}, collision : {type : boolean, default : false} }); the casecontent property filled model of 1 of schemas, 1 exemple : var treeschema = new mongoose.schema({ applecount : {type : number, default : 3} }); treeschema.methods.dostuff = function (data) { console.log('hey, listen'); homecoming true; }; then, want utilize method of schema original container : caseschema.methods.dostuff = function (data) { if (this.casecontent.dostuff !== undefined) { this.casecontent.dostuff(); console.log('it worked'); } else { ...
