Something like this:

<ItemsControl ItemsSource="{Binding DaysOfWeek}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <UniformGrid Rows="1"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <ItemsControl ItemsSource="{Binding HoursInDay}">
                <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <UniformGrid Columns="1"/>
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
            </ItemsControl>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

This assumes you have a collection called DaysOfWeek in your data context (ie. in your main view model). Each DayOfWeek object would expose an HoursInDay collection (likely the same shared collection).

Having said all that, what is the advantage to data-driving this? Is your matrix likely to change in dimensions? If not, why not just "hard-code" the matrix in your view? Each matrix cell can still bind to an appropriate data item in your view model.
