TCL throws invalid command name when writing csv data to a matrix within a namespace -



TCL throws invalid command name when writing csv data to a matrix within a namespace -

this bizarre issue can't seem figure out. using tcl 8.5 , trying read info csv file matrix using csv::read2matrix command. however, every time it, says matrix trying write invalid command. snippet of doing:

package require csv bundle require struct::matrix namespace eval ::iostandards { namespace export * } proc iostandards::parse_stds { io_csv } { # create matrix puts "creating matrix..." struct::matrix iostdm # add together columns puts "adding columns matrix..." iostdm add together columns 6 # open file set fid [open $io_csv r] puts $fid # read csv matrix puts "reading info matrix..." csv::read2matrix $fid iostdm {,} close $fid }

when run code in tclsh, error:

invalid command name "iostdm"

as far can tell, code right (when don't set in namespace. tried namespace import ::csv::* ::struct::matrix::* , didn't anything.

is there missing these packages? nil on wiki.tcl.tk website mentions of sort, , man packages packages don't mention beingness called within namespace.

the problem iostdm defined within iostandards namespace. means, should referenced iostandards::iostdm, , how should pass csv::read2matrix:

csv::read2matrix $fid iostandards::iostdm {,} update

i noticed hard-coded adding 6 columns matrix before reading. improve way tell csv::read2matrix expand matrix automatically:

csv::read2matrix $fid iostandards::iostdm , auto

csv tcl

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...
