assert_checktrue

Parameters

condition:

a matrix of booleans

flag :

a 1-by-1 matrix of boolean, %t if condition is true, %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 all entries in condition are true.

Generates an error if any entry in the condition matrix is false. Generates an error if condition is not a boolean.

If any entry in condition is false,

• 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 which pass
assert_checktrue ( %t );
flag = assert_checktrue ( %t )
[flag,errmsg] = assert_checktrue ( %t )
[flag,errmsg] = assert_checktrue ( [%t %t] );

// Tests which fail
assert_checktrue ( [%t %f] );
flag = assert_checktrue ( [%t %f] )
// No error generated
[flag,errmsg] = assert_checktrue ( [%t %f] )

// Wrong calls
assert_checktrue ( "a" )
