It looks like your network was not saved in your mat file. What code did you use to create the mat file? Had your network variable been created at the time you create the mat file?
Here's an example from this answer.
load breakersize2.mat
out = net([1;1])
out = 1.0344

i didn't use code to generate the ANN. This is what I have done
(1) define variable "input" and "output"
(2) nftool
(3) import data in neural network window
(3) train
(4) export to workspace (the problem is only struct file is getting transfer to the workspace)

Suppose that you exported from nftool to the variable named results then
net = results.Network;

Fine. Then after you get results extract Network from it into net and save it to a mat file just so that you can still l file to load()

x = rand(4,241);
y = randi(3, 1, 241);
nftool
%Import -> Import Data, select x and y, Observations in Columns, OK
%Train
%Export Model -> Export to Workspace, variable named results
net = results.Network;
predicted_y = round(net(x));
accuracy = mean(y == predicted_y) * 100 %percent
