隐函数画图 matlab
请问下怎样才能将('(1-sqrt((18960-((60-L*sino)+11*sin0.7854)^2)-(L^2)*(1-coso)^2)/121)-cos0.7854')=0；
中o（角度）与L的关系求出来挖.
总是出现错误
Error using ==> char
Cell elements must be character arrays.

你试试以下程序：
syms theta L
solve('(1-sqrt((18960-((60-L*sin(theta))+11*sin(0.7854))^2)-(L^2)*(1-cos(theta))^2)/121)-cos(0.7854)',L)
结果为：
