what doas this operator /// mean in matlab ?

syms  p211  p212  p213 p221  p222  p223 p231  p232  p233 gamma p111  p112  p113 p121  p122  p123 p131  p132 p133 y7 y8 y9

   T= -inv([p211  p212  p213 ;p221  p222  p223; p231  p232  p233]) * inv(diag([0.0098;0.0098;0.0176]))' * [p111  p112  p113 ;p121  p122  p123; p131  p132  p133]*[y7;y8;y9]

it returns a matrix 3x1 contains this operator ///

That was a bug in some versions of MATLAB. It is not an operator: it is a representation of the character sequence \ followed by carriage return followed by linefeed, which the underlying symbolic engine uses to indicate continuation onto a new line. The interface was failing to remove those sequences from the output displayed.

thank you Walter Roberson, will it works if i just delete this symbol ?

[Walter Roberson]

It is a display artifact not present in the symbolic expression. It will not affect computation.

For display you can do

regexprep( char(T), '\\\\\\r\\n', '' )

but if you do this you will probably end up with something that starts with

matrix([...])

instead of clean output. But you can do

disp(char(arrayfun(@(EXPR) regexprep( char(EXPR), '\\\\\\r\\n', '' ), T, 'uniform', 0)))
