X = tensor(1:24,) %<- Create a 3 x 4 x 2 tensor. The function disp can be used to display a tensor and correctly displays very small and large elements. Similar to symmetrize, a collection of modes can be passed as a second argument. X = tensor(rand(3,2,3)) Īdditionally, one can check for symmetry in tensors with the issymmetric function. diy shock prank vintage 70s posters car girls picture orbit ode matlab g3 parts kit vocabulario 2 worksheet answers comcast business gateway bridge mode. W = tensor(rand(4,4,4)) Ī second argument can also be passed to symmetrize which specifies an array of modes with respect to which the tensor should be symmetrized. The new, symmetric tensor is formed by averaging over all elements in the tensor which are required to be equal. Symmetrizing and checking for symmetry in a tensorĪ tensor can be symmetrized in a collection of modes with the command symmetrize. Permute(X,1) %<- Call permute with *only* one dimension. X = tensor(1:4,4) %<- Create a 1-way tensor. Permuting a 1-dimensional tensor works correctly. Use permute to reorder the modes of a tensor X = tensor(1:24,) %<- Create a tensor. ans is a tensor of size 2 x 3 x 2Ĭ = tensor(floor(5*rand(2,3,2))) %<- Create another %<- Elementwise means for A, B, and C. ans is a tensor of size 2 x 3 x 2Ģ 2 %<- Max of A and B, elementwise. This can be used for any function that is not predefined for tensors. The function tenfun applies a specified function to a number of tensors.

Using tenfun for elementwise operations on one or more tensors ans is a tensor of size 2 x 3 x 2Ī./B %<- Calls rdivide (but beware divides by zero!) ans is a tensor of size 2 x 3 x 2 ans is a tensor of size 2 x 3 x 2Ī./2 %<- Calls rdivide. ans is a tensor of size 2 x 3 x 2Ī.\B %<- Calls ldivide. ans is a tensor of size 2 x 3 x 2Ī.^2 %<- Calls power. ans is a tensor of size 2 x 3 x 2Ī.^B %<- Calls power. ans is a tensor of size 2 x 3 x 2ĥ*A %<- Calls mtimes. ans is a tensor of size 2 x 3 x 2Ī.*B %<- Calls times. ans is a tensor of size 2 x 3 x 2Ī-B %<- Calls minus. ans is a tensor of size 2 x 3 x 2Ī+B %<- Calls plus. ans is a tensor of size 2 x 3 x 2Ī<=B %<- Calls le. ans is a tensor of size 2 x 3 x 2Ī
