What is the function or syntax for find out adjoint matrix in matlab? I want to find out adjoint matrix... I write syntax Adjoint (A), but this syntax Adjoint (A) is error and the output is 'Undefined function 'adjoint' for input argument type 'double'. Why is error? Give me solution, please... Thank's.

[Steven Lord]

Symbolic Math Toolbox has had an adjoint function since release R2013a.

[ihsan ghafoor]

[Walter Roberson]

Perhaps you do not have the Symbolic Mathematics Toolbox installed?
