matlab - Construct matrix according to the arrangement in another matrix -

-

i have matrix 'eff_tot' dimension (m x n) want rearrange according matrix called 'matches' (e.g. [n2 n3; n4 n5]) , put collumns not specified in 'matches' @ end.

that is, want have [eff_tot(:,n2) eff_tot(:,n3) ; eff_tot(:,n4) eff_tot(:,n5) ; eff_tot(:,n1)].

that's folks!

taking example in first answer, have is:

eff_tot =

81    15    45    15    24 44    86    11    14    42 92    63    97    87     5 19    36     1    58    91 27    52    78    55    95 82    41     0     0     0 87     8     0     0     0  9    24     0     0     0 40    13     0     0     0 26    19     0     0     0

regards.

create vector listing indices of columns in eff_tot , use setdiff determine columns not occur in [n2 n3 n4 n5]. these columns unmatched ones. concatenate matched , unmatched column indices create column-reordered eff_tot matrix.

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
