Before the installation of things, because of a system, re-installed when found to solve the problem is not recorded, again encountered when it will take a lot of time to find solutions, alas.Title, the problem that occurs when using matplotlib this probably means that Tcl wasn ' t installed properly, complete the error prompts as follows:I put the key place box out, in fact, is the version of the reason. Then the workaround is as follows:Locate/

Introduction: a namespace is a collection of commands and variables, the namespace encapsulation ensures that they do not affect other namespace variables and commands. TCL always maintains a global namespace that contains all global variables and

I remember that when I used ruby1.9.x in OS X10.8, I just had to download and install ActiveTcl8.5, and run TK well without any configuration. But recently want to re-execute the TK code, found in require ' TK ' when the error bird! The ruby2.1.3 version is now in use. Search the Internet, the version after 1.9.x no longer TCL/TK support compiled into Ruby, so if you want to use it must be recompiled ruby! I'll take a walk! Can't you make a gem? But i

The biggest advantage of Modelsim's Tcl is that it allows the entire simulation to run automatically, saving you from the trouble of performing various user interface control operations each time. With TCL, You can automatically create databases, map databases to physical directories, and compileSource code, Start the simulator, run the simulation and a series of other operations. The following describes t

　　expr is for Tcl-to-do math type operations. It takes all of its arguments ("2 + 2" for example) and evaluates the result as a Tcl "expression", and returns the value. Many commands expr use behind the scenes of order if to evaluate test expressions, such as, and loops. for tip: enclosing the arguments to in expr curly braces would result in faster code. So do expr{$i*10} instead of simplyexpr$i*

Oracle DDL, DML, DCL, and TCL summarize the impetuousness of some time ago. I always think this will happen too. But when I wake up, I find that I don't know anything, and I don't even know the basic concepts, let's start from scratch and study for a period of time. Oracle learning can be implemented and maintained independently. Of course, optimization is a long time-consuming experience and requires more experience. Www.2cto.com contains some online
