How to create a datastore out of workspace data?

I have a .mat file which has input and output matrices for a neural network that I am making. Each matrix (input, output) is of dimension 2000x3 size. I tried using keyValue datastore to create a datastore out of it, but it is returning a single cell as output. Can anyone please help me out in this regard?

can you share your mat file (or a subset of it)?

There's actually two types of matrices, in1, in2, in3 so on and so forth, and out1, out2, out3 so on an so forth, in and out are the input and output responses for the network. Each matrix is 2000x3 dimension. They all contain numerical data, they aren't related to images text or anything of that sort. I'll try to upload my mat files, but currently my network connection is a bit poor, so it may take some time

You might want to use the arrayDatastore type with the "OutputType" name value. The documentation has examples to help in your use case.
