Vector family obtained by tensorization of a scalar family.
The tensorization is done the following way: if \((f_1,...,f_r)\) is the family of scalar functions, the tensorized family of rank N is given by (where all vectors are columns of size N):
\(\left(\begin{array}{c}f_1\\0\\\vdots\\0\end{array}\right)\); \(\left(\begin{array}{c}f_2\\0\\\vdots\\0\end{array}\right)\);...; \(\left(\begin{array}{c}f_r\\0\\\vdots\\0\end{array}\right)\); \(\left(\begin{array}{c}0\\f_1\\0\\\vdots\\0\end{array}\right)\); \(\left(\begin{array}{c}0\\f_2\\0\\\vdots\\0\end{array}\right)\);...; \(\left(\begin{array}{c}0\\f_r\\0\\\vdots\\0\end{array}\right)\);...; \(\left(\begin{array}{c}0\\\vdots\\0\\f_1\end{array}\right)\);...; \(\left(\begin{array}{c}0\\\vdots\\0\\f_r\end{array}\right)\)
The gradient values are therefore matrices of size N*r, where the gradients of the scalar functions are put in rows:
\(\left(\begin{array}{c}(\nabla f_1)^t\\0\\\vdots\\0\end{array}\right)\); \(\left(\begin{array}{c}(\nabla f_2)^t\\0\\\vdots\\0\end{array}\right)\);...; \(\left(\begin{array}{c}(\nabla f_r)^t\\0\\\vdots\\0\end{array}\right)\); \(\left(\begin{array}{c}0\\(\nabla f_1)^t\\0\\\vdots\\0\end{array}\right)\); \(\left(\begin{array}{c}0\\(\nabla f_2)^t\\0\\\vdots\\0\end{array}\right)\);...; \(\left(\begin{array}{c}0\\(\nabla f_r)^t\\0\\\vdots\\0\end{array}\right)\);...; \(\left(\begin{array}{c}0\\\vdots\\0\\(\nabla f_1)^t\end{array}\right)\);...; \(\left(\begin{array}{c}0\\\vdots\\0\\(\nabla f_r)^t\end{array}\right)\)
