neural network regression model error

i used the following data to generate a dataset nd to train the network as shown but is getting the following error can someone help why this error comes

x = rand(1000,1);

y = sin(x)

options = trainingOptions('adam','Plots','training-progress','MaxEpochs',100)

net = trainNetwork(transpose(x),transpose(y),layers_1,options);

ERROR:

Training on single CPU.

As I understand, your input dataset, “x” has size 1000 x 1 and the output, “y” has size 1000 x 1 and you are defining a regression model for predicting “y”.

In your model, the number of neurons in the last FC layer should match the dimension of “y”. Since, your output is 1-dimensional, the output size of the last Fully Connected (FC) layer used should also be 1. In case, your output “y” is of size 1000 x 2, then the output size of the FC layer should be 2.
