You cannot do that. The result of imagesc is an OOP object, and OOP objects cannot be written to excel files.
Perhaps for your purposes it would be good enough to change
z = imagesc(n);
z = rescale(n);

Error is as above picture

This is not very clear, it would be better to copy the code instead of figures and provide a sample file so that the case can be reproduced. However, there is a clear error in the following:
When you do z=imagesc(n) you are using z as a handle to the image that will be generated with imagesc, for instance:
AlphaData: 1 AlphaDataMapping: 'none' BeingDeleted: off BusyAction: 'queue' ButtonDownFcn: '' CData: [65×65 double] CDataMapping: 'scaled' Children: [0×0 GraphicsPlaceholder] Clipping: on ContextMenu: [0×0 GraphicsPlaceholder] CreateFcn: '' DeleteFcn: '' HandleVisibility: 'on' HitTest: on Interpolation: 'nearest' Interruptible: on Parent: [1×1 Axes] PickableParts: 'visible' Selected: off SelectionHighlight: on Tag: '' Type: 'image' UserData: [] Visible: on XData: [1 65] YData: [1 65]
Clearly that is not what you want to save as an excel file.

Back to the same point z is a handle to the image, but if you want to output that as a file (say a png) you do not use imwrite like that, try this
