brede_mat_submatrix - Pick out submatrix
Mout = brede_mat_submatrix(Min, 'PropertyName', 'PropertyValue')
Input: Min 'Mat' structure
Property: Columns [ integer | {size(Min.matrix,2)} |
allnnan ] indices
for columns. The default is all columns
Description String for description of structure
Rows [ integer | {size(Min.matrix,1)} |
allnnan ] indices for
rows. The default is all rows
Output: Mout Submatrix as 'mat' structure
Construct a submatrix from a matrix.
The 'rows' and 'columns' properties should speficify the
row and column indices to include.
If 'rows'='allnnan' then all rows without any NaN in each
the column element will be included in the output. Also if
'columns'='allnnan' all columns withon any NaN in each of
the row element will be extracted to the output.
Example:
m = [1 10 100 1000]'*[ 1 2 3]
M = brede_mat_submatrix(m, 'Columns', [2 3])
M.matrix
M = brede_mat_submatrix(m, 'Rows', [3 1], 'Columns', [2 3])
M.matrix
m(2,3) = NaN
M = brede_mat_submatrix(m, 'Rows', 'allnnan')
M.matrix
