नमस्कार दोस्तों आज हम आपके लिए ले कर आये है बहुत ही रोचक matlab command जो की आपको दिल की संरचना बनाना बताएगा। साथ ही साथ आप किस तरह linespace , colormap , आदि बहुतो का किस तरीके से उसे किया जाता ह बताया गया है। आप कैश तो इस कमांड को कॉपी पेस्ट भी कर सकते है। परन्तु सबिनम्र निवेदन है कि matlab comand में खुद लिखे और रन करे साथ ही साथ हर example से 5 नए question बनेवे।
