Hi there,
I am using subs to replace some symbols in a symbolic expression Jacobian_mtx_1. The symbols that I want to be replaced are A, B and C, which are a 6*1 symbolic vector, a symbolic scalar, and a 2*1 symbolic vector, respectively. I write the code:
Jacobian_mtx_1 = subs( Jacobian_mtx_1 , { A , B , C } , { A_val ,B_val , C_val } ) ;
where A_val is a 6*1 vector containing 6 function calls, B_val is a numeric scalar, and C_val is a 2*1 numeric vector.
However, the software reminds me that
Errors using sym/subs
Entries in second argument must be scalar.
Could anyone tell me how to resolve this issue?
Many thanks!Hi there,
