With Maple 18.02 and 2017.2 on OSX 10.13.6: 

restart: 
int( exp(a*exp(I*x)) ,x=-Pi..Pi); 
                               0 

but we get the correct answer for numerical a, e.g. 

restart: 
int( exp(1*exp(I*x)) ,x=-Pi..Pi); 
                              2 Pi 

Is this fixed in version 2018.1?

Way i get the wrong output with procedure S1(uu)
 

How can I get the vlaue of matric c?

Thanks for your help

This is my first problem with Maple but i am pretty confused as to why it would struggle with these steps.

Just using a standard worksheet, here is what i have:

> f:=(4^x)+1

>g:=x^4

> solve(g=f,x)

now, i would just expect this to come back with 3 answers, but instead i get 

Warning, solutions may have been lost
                     RootOf(-4^_Z - 1 + _Z^4)

if I do:

>fsolve(g=f,x)

It comes back with only one of the answers(2.094012853), instead of all three.

What am I doing wrong?

I mean, for example,

solve({4*x1+7*x2+6*x3 = 186, floor((1/2)*x1)+floor((1/5)*x2)+floor((1/3)*x3) = 18, 
floor((1/5)*x1)+floor((1/2)*x2)+floor((1/4)*x3) = 21});
Warning, solutions may have been lost

A finite number of the solutions can be found by DirectSearch

DirectSearch:-SolveEquations([floor((1/2)*x1)+floor((1/5)*x2)+floor((1/3)*x3) = 18, 
floor((1/5)*x1)+floor((1/2)*x2)+floor((1/4)*x3) = 21, 4*x1+7*x2+6*x3 = 186], 
{x1 >= -100, x2 >= -100, x3 >= -100, x1 <= 100, x2 <= 100, x3 <= 100}, 
AllSolutions, solutions = 3, number = 1000);

I am trying to solve a set of differential equations in maple. The maple code:

de1:=diff(u1(x,t),x)=-h*(u1(x,t))+i*exp(-i*t)*(u2(x,t));
              d
       de1 := -- u1(x, t) = -h u1(x, t) + i exp(-i t) u2(x, t)
              dx

> de2:=diff(u1(x,t),t)=(-h-i/2)*u1(x,t)-h*exp(-i*t)*u2(x,t);

         d
  de2 := -- u1(x, t) = (-h - 1/2 i) u1(x, t) - h exp(-i t) u2(x, t)
         dt

> dsolve({de1,de2},{u1(x,t),u1(x,t)});
 

However, when I execute it, maple show "Warning: system is consistent". How to remove it

I have a matrix 50*500000 was computed through a loop. when I double click on it I faced with the following error.

Rtable browser error

unable to display structured data

What the problem is?

I asked a question about importing a matrix with symbolic entries the other day.  Just got email saying there had been a reply.  But I can't find my question or that reply!  ............Edgar

Hi,

I would like to translate a set of ODEs from Maple to FORTRAN and optimize them. The problem is that even I have all the equations in one file the maple uses some names in optimizations same as what it has used before. How can I fixed it?

for Example:

with(codegen, optimize, makeproc, cost, prep2trans):

Fortran(eq_dP_5, optimize, resultname = fp1);
      t2 = int(z5 ** 2)
      t3 = int(t2 ** 2)
      t5 = int(z4 ** 2)
      t6 = int(x ** 2)
      t8 = x - 1
      t9 = t8 ** 2
      t10 = 1 / t9
      t11 = t10 * t6 * t5
      t13 = int(mTh ** 2)
      t23 = 2 * z2 * x + z4 * x - 2 * z2
      t26 = 1 / z4
      t32 = Az5 ** 2
      t38 = int(z6 ** 2)
      fp1 = -dble(z4) / dble(t23) / dble(t8) * (dble(t11 * t3 * LmdSF) +
     # dble(2 * t11 * t13 * t2) + dble(2 * t26 / Az5 * t23 * Bz5 * z6 *
     #t8) - 0.16D2 * dble(t10) * t32 * z1 * dble(t6) * dble(t5) * 0.3141
     #592654D1 - dble(2 * t26 * t38 * t23 * t9 * x) + dble(4 / x * t26 *
     # t8 * z2)) * (z1 + valrho) / 0.4D1

Fortran(eq_dmu_5, optimize, resultname = fmu2);
      t1 = z6 ** 2
      t2 = z4 / 0.2D1
      t5 = x ** 2
      t6 = t5 ** 2
      t28 = z5 ** 2
      t29 = t28 ** 2
      t32 = Az5 ** 2
      t35 = mTh ** 2
      t39 = z4 ** 2
      t49 = (x - 1) ** 2
      t50 = t49 ** 2
      fmu2 = (t1 * (z2 + t2) * t6 * dble(x) - 0.5D1 * t1 * (z2 + 0.2D1 /
     # 0.5D1 * z4) * t6 + 0.10D2 * (z2 + 0.3D1 / 0.10D2 * z4) * t1 * t5
     #* dble(x) - 0.10D2 * (z2 + z4 / 0.5D1) * t1 * t5 + ((0.5D1 * z2 +
     #t2) * t1 + 0.4D1 * (LmdSF * t29 / 0.16D2 + t32 * 0.3141592654D1 *
     #valrho + t35 * t28 / 0.8D1) * t39 * z4) * dble(x) - z2 * t1) * dbl
     #e(x) / dble(t50)

Is there a simple (i.e. without using of op( ), coeff( ), etc.)  way to force Maple to put a common constant out of brackets in the expression like 2*a+2*b -> 2(a+b)? The task seems as very simple. But I can't find a solution

I've tried alot, but nothing seems to work. The problem occurres whenever im trying to use multiple SI Units in caculations that require division. Example:
