我嘗試用list把x添加到list里面，但是輸出是[matrix([[0.37160519]]), matrix([[0.37160091]]), matrix([[0.37159685]]), matrix([[0.371593]]), matrix([[0.37158934]]), matrix([[0.37158587]]), matrix([[0.37158256]]), matrix([[0.3715794]]), matrix([[0.37157639]]), matrix([[0.37157351]]), matrix([[0.37157076]]), matrix([[0.37156813]]), matrix([[0.37156561]]), matrix([[0.37156319]]), matrix([[0.37156086]]), matrix([[0.37155863]])]，怎么樣才能把得到的X畫到一張圖里呢？謝謝

uj5u.com熱心網友回復：
首先你要找一個可以進行位圖操作的圖形庫，然后以點陣方式寫入每個像素點的顏色值轉載請註明出處，本文鏈接：https://www.uj5u.com/qita/127554.html
