#Mathematica clear variables code#

(My complaints about mathematica (mine is V4) begin with: the system doesn't follow elementary documentation rules: What are all the inputs, what are all the outputs. There is a general advice against the use of subscripts - as Sander did, because. For example, sage: var('a,b') (a, b) sage: xa+b sage: x a + b sage: var(x) a + b sage: x a + b sage: xx sage: x a + b Here, I assigned a+b to x. Is there any documentation of CleanSlate? My system _has_ CleanSlate, but it's not described in any of the Help stuff. It does not find that 25 MB! The second call to FindMinimum starts with 25 MB. The memory in use builds up to about 25 MB and does not lessen after FindMinimum exits. clearvars -except keepVariables removes all variables, except for those specified by keepVariables.

If any of the variables are global, clearvars removes these variables from the current workspace only, leaving them accessible to any functions that declare them as global. clears values and definitions for any symbols that are equal to or whose names match any of the spec i. Then FindMinimum is called for the first time. clearvars variables removes the variables specified by variables. Usually, once the variable is defined it will be of blue color and once it executed (by pressing Shift+ Enter) it will change color to black.

At this point the CleanSlate utility is loaded, and so this is the state that CleanSlate should return to. Follow this post Suppose that I have an code which goes like this: yp 2 yp 2 a x + yp + yp Please put y with subscript p, NOT Subscript y, p. Before the first call to FindMinimum, the memory in use is about 1 MB. Look at the 'memory in use' numbers and the call to CleanSlate. One of them consistently fails when the other notebook is open, despite my (liberal) use of Clear to clear out the relevant variables.

Both work fine when theyre the only notebook open. Then FindMinimum fits the curve to the data by minimizing 'error'. I have two different Mathematica notebooks with similar, but different functions. The module 'error' finds the total sum-of-squares of distances from the data points to a curve. It fits a 2-parameter curve (a simple Bezier curve) to some data. The notebook below begins with $HistoryLength=0.
