fortran - Assigning Values to the Array ipntr in ARPACK -

-

I am trying to figure out how many values ​​are assigned to an array called IPentrat, which points to ARPAC Do Store. I'm relatively new to Fortran and I do not know how the values ​​of this array are initially set. The code I see is an unmatical driver example which is distributed with ARP and the part I can not understand. 

  Program dndrv1 integer maxn, maxnev, maxncv, ldv parameter (maxn = 256, maxNav = 12, maxncv = 30, ldv = msn) cc% ---------- ----% c | Local arrays. C% --------------% c integer iparam (11), ipntr (14) logical selection (maxncv) double accuracy & amp; Ax (Max), D (MaxNCV, 3), Resid (Maxon), & amp; V (Ldv, maxncv), workdate (3 * maxN), & amp; Cupid (3 * max NCV), & amp; Workclam (3 * maximum NCV * maximum NCV + 6 * maximum NCV) cc% ---------------% C | Local Scalers | C% ---------------% C character bmat * 1, which is * 2 integer IDO, N, NX, NY, NCV, Larkal, information, J, & amp; IARR, Encore, Maxiter, ISHFT, Mode Double Specense & amp; Tol, sigmar, sigmai logical first, raves cc% ------------% c | Parameter | C% ------------% C Double Accuracy & amp; Zero parameter (Zero = 0.0D + 0) cc% -----------------------------% c | Blaze & amp; LAPACK used daily. C% -------------------------% C Double Accuracy & amp; Dlapy2, dnrm2 external dlapy2, dnrm2, daxpy c c% --------------------% c | Internal function | C% --------------------% c Enter the internal entry (*, *) ipntr   
 is the result of the statement to write :  
 1606679396 32767 1606696480 32767 1606918048 32767 0 0 0 0 0 0 0 0  
 Obviously there is nothing like ipntr (1) = 1606679396, how to specify these values has been done?  
 Thank you   
 
 
 If they are not assigned anywhere, their values ​​will be Determined by the random byte sequence which also resides in memory. You should see that running the program again will have a different output sequence.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
