SELCELLS Select cells from expression.
[ CIND ] = SELCELLS( SIN, S_EXPR ) Returns index to cells CIND which fulfill the selection expression S_EXPR. If a sdim field is not found in the input struct SIN the default coordinate names x, y, and z will be used. MODE either indicates selection critera applied to all (MODE 1, default) or any cell vertices (MODE 2).
Input Value/(Size) Description ----------------------------------------------------------------------------------- sin struct Grid or problem struct with p, c (and s) fields s_expr string Cell selection string expression mode {1}/2 Selection mode (1 = all, 2 = any vertices) . Output Value/(Size) Description ----------------------------------------------------------------------------------- cind array Array with indicies to cells which cell vertices satisfy the selection expression
cind = selcells( fea, '(x>0.2) & (x<0.5)' );
