assert_checkequal

Check that computed and expected are equal.

Calling Sequence

assert_checkequal ( computed , expected )
flag = assert_checkequal ( computed , expected )
[flag,errmsg] = assert_checkequal ( computed , expected )

Parameters

computed:the computed result

: :expected : the expected result : :flag : a 1-by-1 matrix of boolean, %t if computed is equal to

expected, %f if not

: :errmsg : a 1-by-1 matrix of strings, the error message. If

flag==%t, then errormsg==””. If flag==%f, then errmsg contains the error message.

Description

Performs silently if computed and expected are equal.

If the type of both input arguments is 1 (i.e. a real matrix), we check that non-nan values are equal.

We compare first the real parts. In case of equality, we compare the imaginary parts.

If the comparison shows that computed is equal to expected,

• if the errmsg output variable is not used, an error is generated,
• if the errmsg output variable is used, no error is generated.

Examples

// Tests with success
assert_checkequal ( %T , %T );
flag = assert_checkequal ( `list`_() , `list`_() );
[flag , errmsg] = assert_checkequal ( [%T %F], [%T %F] );
assert_checkequal ( %nan , %nan );

// Tests with failure
assert_checkequal ( %F , %T );
flag = assert_checkequal ( %F , %T );
// No error produced :
[flag , errmsg] = assert_checkequal ( %F , %T )
assert_checkequal ( [1 2], [3 4] )
assert_checkequal ( 1 , [2 3] )
assert_checkequal ( 1 , "b" )
