subtom_join_eigenvolumes

Computes the final sum of projections of the data onto Eigenvectors.

subtom_join_eigenvolumes(
    'eig_vol_fn_prefix', eig_vol_fn_prefix ('class/eigvol_pca'),
    'iteration', iteration (1),
    'num_eigs', num_eigs (40),
    'num_xmatrix_batch', num_xmatrix_batch (1))

Calculates the sum of previously calculated Eigenvolume partial sums, (projections onto previously determined Eigen (or left singular) vectors), which can then be used to determine which vectors can best influence classification. The Eigenvolumes are expected to have been split into NUM_XMATRIX_BATCH sums. The output averages will be written out as given by EIG_VOL_FN_PREFIX, ITERATION and #, where the # is the particular Eigenvolume being written out from 1 to NUM_EIGS. For easier viewing a montage of the Eigenvolumes is made along the X, Y, and Z axes, written out as specified by EIG_VOL_FN_PREFIX, (X,Y,Z) and ITERATION.

Example

subtom_join_eigenvolumes(...
    'eig_vol_fn_prefix', 'class/eigvol', ...
    'iteration', 1, ...
    'num_eigs', 40, ...
    'num_xmatrix_batch', 100)
