calling a function in another function by changing only few input arguments

I have written a function function

 [ yp,PAC ] = PAgent( c5,c6,c7,rcapa,Aineq5,Bineq5,Aeq5,Beq5,lb,ub,options )

suppose if i have to call this function in another function by changing only the input argument 'rcapa', i.e., other input arguments c5,c6,c7.... will not change, but only 'rcapa' changes, can i write like the following,

 PA1 = @(rcapa) PAgent([],[],[],rcapa,[],[],[],[],[],[],[] );
 [yp1,PAC1]= PA1(rcapa);

If you are in another function where variables with the same names are defined (e.g. because they are arguments of the function), but you want to create a wrapper for PAgent as a function of 1 parameter rcapa that calls another function with the same parameters but with this one updated, do it this way:

 function otherFunction( c5,c6,c7,rcapa,Aineq5,Bineq5,Aeq5,Beq5,lb,ub,options ) 

    PA1 = @(rcapa) PAgent( c5,c6,c7,rcapa,Aineq5,Bineq5,Aeq5,Beq5,lb,ub,options ) ;

then you can call PA1 with the specific value of rcapa, but all the other arguments will remain the same as defined by/in otherFunction.

This is like creating an internal function. All variables that are not defined locally come from the nesting/external function. The only internal/local variable in

 PA1 = @(rcapa) PAgent( c5,c6,c7,rcapa,Aineq5,Bineq5,Aeq5,Beq5,lb,ub,options ) ;

is rcapa.
