ReLu 'Activation function' is not a recognized parameter in convolution2dLayer

convolution2dLayer(32, 7, 'Stride', 2, 'Padding', 'same', 'Name', 'conv_1', 'Activation', 'relu')

This is my line code and resulted error below:

Error using convolution2dLayer>iParseInputArguments (line 155)

'ActivationFcn' is not a recognized parameter. For a list of valid name-value pair arguments, see the documentation for this

function.

"Activation" is not a valid input option for convolution2dLayer in MATLAB. In MATLAB, activation functions are specified by connecting the output of the convolution layer to an appropriate activation layer - in this case reluLayer:

convRelu = [...
    convolution2dLayer(32, 7, 'Stride', 2, 'Padding', 'same', 'Name', 'conv_1'); ...
    reluLayer('Name', 'relu_1')]
