Hello everyone,

im new in Julia i have version 1.0 and there is a code that i want to run but it doesn’t want to, actually it i only one code that i want to use in another file and maybe this code was written in 0.0.6

this is the code:

```
type QRelaySym{T<:Tuple}
aH::T
bH::T
aV::T
bV::T
apH::T
bpH::T
apV::T
bpV::T
end
function trans(op, a, b, ap, bp, B)
p = B * [ap; bp]
op = subs(op, a, p[1])
op = subs(op, b, p[2])
return op
end
#2D rotation matrix
function rotmat(theta)
c = cos(theta)
s = sin(theta)
return [c s; -s c]
end
function qrelay_op(n, phi, alpha, delta)
#operators before BS
aH = symbols(@sprintf("a_H1:%d", n+1))
bH = symbols(@sprintf("b_H1:%d", n+1))
aV = symbols(@sprintf("a_V1:%d", n+1))
bV = symbols(@sprintf("b_V1:%d", n+1))
op = 0
for i=1:n
op += phi[i] * (aH[i]*bH[i] + aV[i]*bV[i])
end
B = 1/sqrt(2)*[1 1;-1 1]
apH = symbols(@sprintf("a'_H1:%d", n+1))
bpH = symbols(@sprintf("b'_H1:%d", n+1))
apV = symbols(@sprintf("a'_V1:%d", n+1))
bpV = symbols(@sprintf("b'_V1:%d", n+1))
for i=1:n-1
op = trans(op, bH[i], aH[i+1], bpH[i], apH[i+1], B)
op = trans(op, bV[i], aV[i+1], bpV[i], apV[i+1], B)
end
op = trans(op, aH[1], aV[1], apH[1], apV[1], rotmat(alpha))
op = trans(op, bH[n], bV[n], bpH[n], bpV[n], rotmat(delta))
syms = QRelaySym(aH, bH, aV, bV, apH, bpH, apV, bpV)
return syms, op
end
function op_mat(op)
op = op[:as_poly](domain="C")
op_a = op.x[:gens]
nab = op[:length]()
op_ab = ones(SymPy.Sym, nab)
coef = zeros(Complex, nab)
mat = zeros(Int64, length(op_a), nab)
for (i, (ps, c)) in enumerate(op[:as_dict]())
for (j, p) in enumerate(ps)
mat[j, i] = p
op_ab[i] = op_a[j]^p * op_ab[i]
end
coef[i] = c
end
return op_a, op_ab, mat, coef
end
` ` `
and it shows always this message:
ERROR: syntax: extra token "QRelaySym" after end of expression
```
