matrix calculation error

Question

I am using R tool to calculate SVD (svd(m)) and it works on small matrix but as I pass it 20Kx20X matrix. After processing, it gives the following erro

Answer 1

Possibly the svd calculation itself also uses a lot of memory. If we compare to MATLAB, we see that the svd calculation allocates just as much memory as the matrix itself uses, so if you already ise 3GB of memory, the svd calculation possibly allocates another 3GB, which gives 6GB of memory.
