如何用matlab解下面的方程b=4.73/2.75;a=(asech(4.73)-cos(4.73))/(csch(4.73)-sin(4.73));y=asech(b*x)+cos(b*x)-a*(csch(b*x)+sin(b*x));求解y＝0时的解x＝?我用solve老是出错啊? Undefined function or method 'solve' for input argumen

syms x ;
a=(asech(4.73)-cos(4.73))/(csch(4.73)-sin(4.73));
b=4.73/2.75;
solve('asech(b*x)+cos(b*x)-a*(csch(b*x)+sin(b*x))',x)
======以下答案可供参考======

貌似解不出来
>> solve('asech(b*x) + cos(b*x) - a*(csch(b*x) + sin(b*x))', x)
