Dear group I has a list as form that follow,where a_ii, b_ii and c_ii are numeric values list = {{a11*E^(b11*(t - T) + c11*T) + a12*E^(b12*(t - T) + c12*T) + a13*E^(b13*(t - T) + c13*T)}, {a21*E^(b21*(t - T) + c1*T) + a22*E^(b22*(t - T) + c2*T) + a23*E^(b23*(t - T) + c23*T)}}; I want to make a Math function (I call ListTransform) to apply the below transformation for each element of list (a*(E^(b*t) - E^(c*t)))/(b - c) To obtain a list as follow listTransform[list1] = {{(a11*(E^(b11*t) - E^(c11*t)))/(b11 - c11)+(a12*(E^(b12*t) - E^(c12*t)))/(b12 - c12)}, {, ..., ...}} My goald is apply this transformation to follow kind of operation A2 = {{1.1, 2.2}, {3.1, 4.3}}; list2 = Expand[MatrixExp[A2*T] . {3/E^(2.3*t) + 4/E^(2.1*t), 0} /. t -> t - T] listTransform[list2] --------------------------------------------- This message was sent using Endymion MailMan. http://www.endymion.com/products/mailman/
