I'm testing the time frequency tutorial and I got the following error due to the missing function "ismatrix.m" cfg = []; cfg.baseline = [-0.5 -0.1]; cfg.baselinetype = 'absolute'; cfg.maskstyle = 'saturation'; cfg.zlim = [-3e-27 3e-27]; = 'MRC15'; figure ft_singleplotTFR(cfg, TFRhann); ??? Undefined function or method 'ismatrix' for input arguments of type 'double'. Error in ==> rgb2hsv at 12 elseif ismatrix(m) && size(m,2)==3 Error in ==> ft_plot_matrix at 239 hsvcdat = rgb2hsv(rgbcdat); Error in ==> ft_singleplotTFR at 466 ft_plot_matrix(xvector, yvector, datamatrix, 'clim',[zmin,zmax],'tag','cip','highlightstyle',cfg.maskstyle,'highlight', mask) I was using a relatively old matlab ( (R2009b)). Adding the ismatrix function from fileexchange would solve the issue:

RELATIVELY OLD????!!! Ancient, you mean :o). Note, that issues of this kind are typically solved through the compat/matlabltX directories. I see that matlablt2010b (which would apply to your case) already has the isrow and iscolumn functions. Perhaps you could add the ismatrix there?

I indeed recall that functions like these have some historical issue. I think they were first in a (extra) toolbox and only later were moved to standard matlab. If you don't have that toolbox, then it fails. >> which isvector built-in (/opt/matlab/R2009a/toolbox/matlab/elmat/isvector) >> which ismatrix 'ismatrix' not found. >> which isrealmat /opt/matlab/R2009a/toolbox/ident/idutils/isrealmat.m ident = system identification toolbox, I can check relatively easily on mentat whether these functions exist on all matlab versions. Will do. Then they should be added to the respective combat directories.

(In reply to Robert Oostenveld from comment #2) No worries Robert. Given I've a prehistoric matlab version doesn't make any sense to support it . I'll be aware and it's easy to solve. I close this bug but feel free to open it if you disagree

Since we now have a better way of dealing with old matlab version, I think it would be good to organize these functions in a better way. See also which is slightly related. This is what we have at DCCN (up to 2015b) on the cluster: roboos@dccn-c023> ls /opt/matlab/*/toolbox/ident/idutils/isreal* /opt/matlab/R2007a/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2007a/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2007a/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2007b/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2007b/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2007b/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2008a/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2008a/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2008a/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2008b/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2008b/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2008b/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2009a/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2009a/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2009a/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2009b/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2009b/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2009b/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2010a/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2010a/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2010a/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2010b/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2010b/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2010b/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2011a/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2011a/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2011a/toolbox/ident/idutils/isrealvec.m /opt/matlab/R2011b/toolbox/ident/idutils/isrealmat.m /opt/matlab/R2011b/toolbox/ident/idutils/isrealrowvec.m /opt/matlab/R2011b/toolbox/ident/idutils/isrealvec.m Since these disappeared after 2011b, they should not be in external/ident. I will add is matrix to combat/matlablt2010b, which already contains some of these type of functions. roboos@mentat001> git commit [master 4dc111c] ENH - improved support for matlab2009b, see bug 3134 2 files changed, 35 insertions(+) create mode 100644 compat/matlablt2010b/ismatrix.m create mode 100644 test/test_bug3134.m

(In reply to Robert Oostenveld from comment #4) Cool! thanks Robert
