Details:

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
