2021-5-2 · Tensors are higher-order extensions of matrices. In recent work the authors introduced the notion of the t-product ageneralization of matrix multiplication for tensors of order three. The multiplication is based on a convolution-like operation whichcan be implemented efﬁciently using the Fast Fourier Transform (FFT). Based on t-product there has a similar linear algebraicstructure of tensors to matrices. For example there has the tensor SVD (t-SVD) which is computable. By using some properties ofFFT we have a more efﬁcient way for computing t-product and t-SVD in. We develop a Matlab toolbox to implement severalbasic operations on tensors
