how to solve equation

the t values are t=0.128:0.000166:0.25;

the integral value is 55380000.*exp(-t./1000000) - (3337.*exp(-10.*t))./500 - (743.*exp(-t./10))./3 - (21041.*exp(-100.*t))./15000 - (5405.*exp(-t./100))./3 - (1582.*exp(-1000.*t))./9375 - 15010.*exp(-t./1000) - (6413.*exp(-10000.*t))./120000 - (52300.*exp(-t./10000))./3 - (1040869175108567.*exp(-100000.*t))./164926744166400000 - 2552000.*exp(-t./100000) - (1457309204128727.*exp(-1000000.*t))./824633720832000000 - (4667.*exp(-t))./75 - (2424417641687941.*exp(-10000000.*t))./16492674416640000000 - (2661500000.*exp(-t./10000000))./3 + 13761046022159181047526242381./16492674416640000000;

the values of g(e) and lambda i will upload

lambda . is 7.8

the values of g(e) and lambda are in image

Use "fzero" on the equation

Left hand side - right hand side(t) = 0.

( My guess is that you want to solve for t given a pair (lambda,g(e)) )
