<DIV ><B>关于功能函数solve的问题?</B></DIV>
<DIV>小弟有个方程需要解出:<BR>方程为:acosx -bxsinx = c <BR>程序如下:<BR>solve('a*cos(x) - b*x*sin(x) = c')<BR>但得出得解是如下提示:<BR>Warning: Explicit solution could not be found.<BR>> In D:\MATLAB6p5\toolbox\symbolic\solve.m at line 136<BR><BR>ans =<BR><BR>[ empty sym ]<BR>请问高手是不是这个方程中符号常数a,b,c不给定可能无解导致得?还是其他原因?忘赐教!<BR>小弟在此先谢谢了</DIV>
