I am unable to perform the function "load('neuralnet.mat');" using MATLAB 2012a

clear all; clc; clf; close all;
tic
sets =10;
iterations=1;
trials=1;

pop = zeros(12,sets);
for i=1:sets
pop1=randi([10,4000],12,1);
  addi =sum(pop1);  
    while addi <= 24000
        pop1= randi([10,4000],12,1);
        addi = sum(pop1);
    end
    if addi>=24000 
pop(:,i)=pop1;
    end
end
ymin=0;
a =sum(pop,1);
load('neuralnet.mat');
objvalue=sim(net,pop);
obj1=transpose(objvalue);
obj2=0;
yo=0;
[yi,q] =min(obj1);
gbest1 = pop(:,[q]);

I am unable to perform the function "load('neuralnet.mat');" using MATLAB 2012a what may the posible reason.

Apart from this I am getting the the following warning and error message respectivley.

Warning: An error occurred when running a class's loadobj

method. The object that was loaded from the MAT-file was a

copy of the object before the loadobj method was run. The

rest of the variables were also loaded from the MAT-file.

The encountered error was:

Error using nnupdate.net (line 36)

Cannot update network of unrecognized version.

Error using annde (line 22)

'model' parameter must be a string

neuralnet.mat is not part of any Mathworks product, unless it is part of an example that I have not found yet.

You need to create it, or download it from somewhere relevant, such as

https://github.com/Jensen-Lab/AUTOPLANT/tree/main/train_neural_network

or get it from the author of https://pfigshare-u-files.s3.amazonaws.com/1470313/CAGUAetal_revised_20140418.pdf ("Acoustic Monitoring of Blast Fishing")
