clc;
data1= readtable('training.xlsx');
A= table2array(data1);
targetD= categorical(A(:,4));
trainD = (A(:,1:3));
trainDNew = reshape(trainD', [1,3,1,7034]);
layers=[
imageInputLayer([1 3 1], 'Normalization', 'none');
convolution2dLayer([1 200],20,'stride',1);
reluLayer();
maxPooling2dLayer([1 20],'stride',10);
fullyConnectedLayer(4);
softmaxLayer;
classificationLayer];
maxEpochs = 100;
miniBatchSize = 100;
options = trainingOptions('adam', ...
    'ExecutionEnvironment','auto', ...

net = trainNetwork(trainD',targetD,layers,options);

I have a data array for training with 7034 rows and 3 column ( input) and 4th column as output (catagorial). My code is attached. I am receiving the following error:

Eror using trainNetwork (line 170)

Invalid network.

Caused by:

Layer 2: Input size mismatch. Size of input to this layer is different from the expected input size.

Inputs to this layer:

from layer 1 (output size 1×3×1)

Can anyone tell me what is the problem with the input layer. As I have given my input layar like

imageInputLayer([1 3 1]);

I have created a 4D data array using reshape. trainDNew = reshape(trainD', [1,3,1,7034]);

Please help me with this problem.
