i am getting error while predicting image??

img=imread('4.jpg');

>> net=alexnet;

>> predict=classify(net,img)

Error using DAGNetwork/calculatePredict>predictBatch (line 151)

Incorrect input size. The input images must have a size of [227 227 3].

Error in DAGNetwork/calculatePredict (line 17)

Y = predictBatch( ...

Error in DAGNetwork/classify (line 134)

scores = this.calculatePredict( ...

Error in SeriesNetwork/classify (line 502)

[labels, scores] = this.UnderlyingDAGNetwork.classify(X, varargin{:});

Hi,

The issue might be due input image resolution. alexnet expects an input of size 227*227*3. The image you are passing may not be of the same size. Try resizing the image using imresize function to 227*227*3.

Hope this helps
