Error
code
Description
180 Break
The d or c key was pressedduring a long calculation or during program execution.
190 Circular definition
This message is displayed to avoid running out of memory during infinite replacement of
variable values during simplification. For example, a+1->a, where a is an undefined variable,
willcause this error.
200 Constraint expression invalid
For example, solve(3x^2-4=0,x) | x<0 or x>5 wouldproduce this error message because the
constraint is separated by “or” instead of “and.”
210 InvalidData type
An argument is of the wrong data type.
220 Dependent limit
230 Dimension
A list or matrix index is not valid. For example, if the list {1,2,3,4} is stored in L1, then L1[5] is a
dimension error because L1 only contains four elements.
235 Dimension Error. Not enoughelements in the lists.
240 Dimension mismatch
Two or more arguments mustbe of the same dimension. For example, [1,2]+[1,2,3] is a
dimension mismatch because the matrices containa different number of elements.
250 Divide by zero
260 Domain error
An argument must be ina specified domain. For example, rand(0) is not valid.
270 Duplicate variable name
280 Else and ElseIf invalid outside of If...EndIf block
290 EndTry is missing the matching Else statement
295 Excessive iteration
300 Expected 2 or 3-element list or matrix
310 The first argument of nSolve must be an equation in a single variable. It cannot containa non-
valued variable other than the variable of interest.
320 First argument of solve or cSolve must be an equation or inequality
For example, solve(3x^2-4,x) is invalid because the first argument is not an equation.
