 *תפיצו...*
למי שיש לו בעיות עם המשתנים הסימבולים (ומקבל אחרי סימפליפיי משהו באורך
הגלות) במעגלים טיפ מיערה. עוד לא בדקתי את זה, אז אני לא יודע בדיוק איך זה בא
לידי ביטוי במימוש, אבל אני מאמין שזה יכול לסייע.

יש לי תשובה, לפחות חלקית, למה שדיברנו -
כאשר אתה מגדיר משתנה סימבולי במטלב, מטלב מניח אוטומטית שהמשתנה הינו מרוכב.
לכן, כאשר אתה מנסה לקבל את החלק הממשי או המדומה של ביטוי סימבולי, אם מטלב לא
יודע שהמשתנים הינם ממשיים הוא מוסיף או מחסיר את הצמוד (בהתאמה) ומכפיל בחצי
או במינוס חצי i. לכן מתקבלים ביטויים כ"כ ארוכים שלא ניתן לפשט.
כדי לפתור את הבעיה, פשוט הגדר את כל ההתנגדויות, הקיבולים וכו' כמספרים ממשיים
(ואפילו אפשר חיוביים), ורק את האימפדנסים הגדר כמשתנים מרוכבים (unreal).
הביטויים יהיו כעת הרבה יותר פשוטים.
