WebWhat I need to do is to compute the average excluding (set to NaN?), the values in each sub matrix falling outside the upper and lower limits, namely those grater than the mean+standard deviation of the 3x3 matrix and those smaller than the mean-standard deviation of the 3x3 matrix, respectively. WebTo see that the kernel is a subgroup, we need to show that for any g and h in the kernel, g h is also in the kernel; in other words, we need to show that ρ ( g h) = 1. But that follows from the definition of a homomorphism: ρ ( g h) = ρ ( g) ρ ( h) = 1 ⋅ 1 = 1. We leave it to the reader to find the proof that the image is a subgroup of H. grant thornton welcome kit
