Missing input in the argument

clear all; close all;
a=0.35; M=1; r0=0; r1=0; p=0.5; d=0.5; Z=100;

Not enough input arguments.

[Walter Roberson]

K=@(t,p,Z,d,r1) (p*Z-d-exp(-t))*r1;

K is defined needing 5 input parameters.

 V(i) = r0 + ((1-a)./M)*integral(K,0,P(i))+ (a./M)*integral(K,0,P(i));

integral() calls the given function with exactly one input parameter. p, Z, d, r1 are all undefined as far as K is concerned.

If you had defined

 K=@(t) (p*Z-d-exp(-t))*r1;

then the existing numeric values of p, Z, d, and r1 would be "captured" by the function handles, and everything would be fine.
