Unable to execute GA optimisation algorithm due to Objective Function

I am currently trying to optimise resource allocation using GA. Pretty new to Matlab but I need to have this working.

Current code I am using:

x4= 5
x5= 1
x6= 6
x7= 2
x8= 15

w1= 6
w2 = 22
w3 = 3
w4 = 24

LB = [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0];

b=[w1+w2+w3+w4;x1;x2;x3;x4;x5;x6;x7;x8;w1;w2;w3;w4];

A=[***own constraints in here***];

nvars = 32;

opts = -gaoptimset (opts,'TolFun',1e-12,'PopulationSize',100);

ObjectiveFunction = @(v) ResourceAllocation (v,x1,x2,x3,x4,x5,x6,x7,x8,w1,w2,w3,w4);

[v,fval] = ga (ObjectiveFunction,nvars,A,b,[],[],LB,[],[],opts).

Errors I am currently getting:

Undefined function or variable 'ResourceAllocation'.

Error in @(v)ResourceAllocation(v,x1,x2,x3,x4,x5,x6,x7,x8,w1,w2,w3,w4)

Error in createAnonymousFcn>@(x)fcn(x,FcnArgs{:}) (line 11)
fcn_handle = @(x) fcn(x,FcnArgs{:});

Please help

Note: your line

opts = -gaoptimset (opts,'TolFun',1e-12,'PopulationSize',100);

cannot work, as it attempts to do a unary minus on the struct that results from gaoptimset

Your line

[v,fval] = ga (ObjectiveFunction,nvars,A,b,[],[],LB,[],[],opts).

needs to have the period changed to semi-colon

MATLAB cannot find the file where you define your objective function evaluation. If you type:

which ResourceAllocation

MATLAB will tell you which version of the file it finds (if any). IF is not returning to you a location of the file, you need to make sure that this function file is on the MATLAB search path .
