Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
Function: ssearch (<seq>, <string>)
Function: ssearch (<seq>, <string>, <test>)
Function: ssearch (<seq>, <string>, <test>, <start>)
Function: ssearch (<seq>, <string>, <test>, <start>, <end>) Returns the position of the first substring of <string> that matches the string <seq>. Default test function for matching is sequal. If ssearch should ignore case, use sequalignore as test. Use <start> and <end> to limit searching. Note that the first character in <string> is in position 1.
(%i1) ssearch("~s","~{~S ~}~%",sequalignore);
(%o1) 4(%o1) true (%i2)
