Functions

int main(int argc, char *argv[])

aeq [ option ] exfile [ infile ]

• -t double

  • absolute tolerance \((0 \le \epsilon)\)

• -e int

  • error type

    • 0 absolute error

    • 1 relative error

• -L

  • disable to check length

• exfile str

  • double-type expected values

• infile str

  • double-type actual values

• stdout

  • result messages

This command checks whether two data sequences are almost equal or not.

Given the two data sequences

\[\begin{split} \begin{array}{cccc} x_1(0), & x_1(1), & \ldots, & x_1(T_1), \\ x_2(0), & x_2(1), & \ldots, & x_2(T_2), \\ \end{array} \end{split}\]

the absolute error \(e(t)\) is calculated sample-by-sample:

\[ e(t) = | x_1(t) - x_2(t) |. \]

If \(e(t)\) is greater than tolerance \(\epsilon\) or \(T_1\) is not equal to \(T_2\), the command prints a warning message.

The below example checks the equality between two data:

aeq -t 0 data.x1 data.x2

Parameters:

• argc – [in] Number of arguments.

• argv – [in] Argument vector.

Return values:

• -1 – Given two data sequences are not almost equal.

• 0 – Given two data sequences are almost equal.

• 1 – Failed to run this command.
