New in MTEX 3.4 (Mar 14, 2013)

  • New plotting engine:
  • The alignment of the axes in the plot is now described by the options 'xAxisDirection' which can be 'north', 'west', 'south', or 'east', and 'zAxisDirection' which can be 'outOfPlane' or 'intoPlane'. Accordinly, there are now the commands
  • plotzOutOfPlane, plotzIntoPlane
  • The alignment of the axes can be changed interactively using the new MTEX menu which is located in the menubar of each figure.
  • northern and southern hemisphere are now separate axes that can be stacked arbitrarily and are marked as north and south.
  • Arbitrary plots can be combined in one figure. The syntax is
  • ax = subplot(2,2,1)
  • plot(ax,xvector)
  • One can now arbitrarily switch between scatter, contour and smooth plots for any data. E.g. instead of a scatter plot the following command generates now a filled contour plot
  • plotpdf(ebsd,Miller(1,0,0),'contourf')
  • obsolete options: 'fliplr', 'flipud', 'gray',
  • Colormap handling:
  • User defined colormap can now be stored in the folder 'colormaps', e.g. as 'red2blueColorMap.m' and can set interactively from the MTEX menu or by the command
  • mtexColorMap red2blue
  • ODF:
  • The default ODF plot are now phi2 sections with plain projection and (0,0) beeing at the top left corner. This can be changed interactively in the new MTEX menu.
  • the computation of more then one maximum is back. Use the command
  • [modes, values] = calcModes(odf,n)
  • EBSD:
  • MTEX is now aware about inconsistent coordinate system used in CTF and HKL EBSD files for Euler angles and spatial coordinates. The user can now convert either the spatial coordinates or the Euler angles such that they become consistent. This can be easily done by the import wizard or via the commands
  • % convert spatial coordinates to Euler angle coordinate system
  • loadEBSD('filename','convertSpatial2EulerReferenceFrame')
  • % convert Euler angles to spatial coordinate system
  • loadEBSD('filename','convertEuler2SpatialReferenceFrame')
  • It is now possible to store a color within the variable describing a certain mineral. This makes phase plots of EBSD data and grains more consistent and customizable.
  • CS = symmetry('cubic','mineral','Mg','color','red')
  • New option 'sharp' for plotting EBSD maps having a sharp texture that yields optimized contrast in the color map.
  • plot(ebsd,'sharp')
  • New orientation color maps. Colororize orientations according to angle in the (inverse) pole figure. Implements issue https://code.google.com/p/mtex/issues/detail?id=86
  • Better rule of thumb for the kernel width when computing an ODF from individual orientations via kernel density estimation.
  • inpolygon can be called as
  • inpolygon(ebsd,[xmin ymin xmax ymax])
  • Tensors:
  • new command to compute the Schmid tensor
  • R = SchmidTensor(m,n)
  • new command to compute Schmid factor and active slip system
  • [tauMax,mActive,nActive,tau,ind] = calcShearStress(stressTensor,m,n,'symmetrise')
  • it is now possible to define a tensor only by its relevant entries. Missing entries are filled such that the symmetry properties are satisfied.
  • faster, more stable tensor implementation
  • new syntax in tensor indexing to be compatible with other MTEX classes. For a 4 rank thensor 'C' we have now
  • % extract entry 1,1,1,1 in tensor notation
  • C{1,1,1,1}
  • % extract entry 1,1 in Voigt notation
  • C{1,1}
  • To index a list of tensors 'C' use
  • % extract the first tensor
  • C(1)
  • Import / Export:
  • command to export orientations
  • export(ori,'fname')
  • command to import vector3d
  • v   = loadvector3d_generic('fname','ColumnNames',{'x','y','z'})
  • v   = loadvector3d_generic('fname','ColumnNames',{'latitude','longitude'})
  • new interface for DRex
  • new interface for Rigaku
  • new interface for Saclay
  • new interface for Oxford .csv data. Implements issue https://code.google.com/p/mtex/issues/detail?id=91
  • General:
  • improved instalation / uninstalation
  • new setting system
  • setpref('mtex','propertyName','propertyValue')
  • has been replaced by
  • setMTEXpref('propertyName','propertyValue')
