Both Octave and Matlab return false for strcmp('abc',strvcat('a','b','c')) so I would assume the issue is not that widespread.

Not sure which other functions to test for. Out of curiosity, I tried this in Matlab

>> f=figure(['color']',[1 1 1])
f =
  Figure (1) with properties:

Octave chokes on it:

octave> f=figure(['color']',[1 1 1])
error: set: ambiguous figure property name c; possible matches:
children          closerequestfcn   colormap          currentaxes       currentobject
clipping          color             createfcn         currentcharacter  currentpoint

I'm not sure this really matters though...

Thanks for your feedback.

For the char array input, I guess this is related to what is described in bug #49536.

For the 1xN vs Nx1 vector, I agree with you. I came across this with an evaluated string that was obtained from reading from a file with fread(fid,'char*').

In Octave the string input of the eval function has to be a 1xN array while Matlab allows 1xN and Nx1. Matlab throws an error if the input is MxN while Octave will execute the first row.

Matlab:

>> str = 'disp(''hello'')'

str =

disp('hello')

>> eval(str)
hello
>> eval(str')
hello
>> str = strvcat('disp(''hello'')','disp(''hi'')')

str =

disp('hello')
disp('hi')

>> eval(str)
Error: Unexpected MATLAB expression.

>> eval(str')
Error: Unexpected MATLAB expression.

Octave:

> str = 'disp(''hello'')'
str = disp('hello')
> eval(str)
hello
> eval(str')
error: 'd' undefined near line 1 column 1
> str = strvcat('disp(''hello'')','disp(''hi'')')
str =

disp('hello')
disp('hi')

> eval(str)
hello
> eval(str')
error: 'dd' undefined near line 1 column 1
