I can't load my own dataset!

I am having a feature vector of 1X83 and a target matrix of 5X83 and both of them are in .mat format i wanted to creat a dataset that contains them just like this: [ x, t ] = iris_dataset;

so how to create a dataset like iris_dataset?

A little help will be very appreciated please

I don't know. For the last 15 years I have just used

 x = input;
 t = target;

Hope this helps.

Ok how to use this if i want to run this code:

[x,t] = digit_dataset;

Train an autoencoder with a hidden layer of size 10 and a linear transfer function for the decoder. Set the L2 weight regularizer to 0.001, sparsity regularizer to 4 and sparsity proportion to 0.05.

rng('default')
hiddenSize = 10;
autoenc1 = trainAutoencoder(X,hiddenSize,...
    'L2WeightRegularization',0.001,...
    'SparsityRegularization',4,...
    'SparsityProportion',0.05,...
    'DecoderTransferFunction','purelin');

here i want to replace the digit_dataset with my dataset please. so what do you suggest?

function [x, t] = digit_dataset
  datastruct = load('MatFileThatYourDataIsIn.mat');
  x = datastruct.x;
  t = datastruct.t;
end

Thank you so much . The thing is im having two files .one is for the feature vectors.mat and the other is for the target.mat ,so how to combine them together in one file. Should i use the dataset command ?

[Walter Roberson]

function [x, t] = digit_dataset
  datastruct_x = load('MatFileThatYourXDataIsIn.mat');
  x = datastruct_x.x;
  datastruct_t = load('MatFileThatYourTDataIsIn.mat');
  t = datastruct_t.t;
end

They do not need to be in the same data structure at any time.

Thank you soooo much you saved my day

I still don't see why you feel it is absolutely necessary for you to have to use the first and last commands, i.e., use a function.

It's just an option. Correct?
