Input:
pdsolve(ds(y,t)-ds(y,x,0.5)=2y)

Write:
`pdsolve(ds(y,t)-ds(y,x,0.5)=2y)`



Compute: $$pdsolve(\frac{dy}{dt} -\frac{d^{{0.5}}y}{dx^{{0.5}}}=2\ y)$$

Output: $$ pdsolve(\frac{dy}{dt} -\frac{d^{{0.5}}y}{dx^{{0.5}}}=2\ y) == C_1\ exp(2\ t)\ (1-t-1.1283791670955126\ \sqrt{x})+C_1\ E_{0.5} ((-2)\ \sqrt{x})\ (1-t-1.1283791670955126\ \sqrt{x}) $$ Result:$$C_1\ exp(2\ t)\ (1-t-1.1283791670955126\ \sqrt{x})+C_1\ E_{0.5} ((-2)\ \sqrt{x})\ (1-t-1.1283791670955126\ \sqrt{x})$$
