Alglib CMatrixDouble.Set

[Pär Lansåker]

The last Alglib update, sept 30 made my, indicator crash:

CMatrixDouble cX;
cX.Resize(L,K);
cX[j].Set(k, y[k + j]);   //j<L, k+j < K

Improperly formatted code edited by moderator.

It doesn't affect cX.

Is there a problem?

Please report the MetaTrader build ... How to report technical issues

The current officially released MT5 build is 4000. Anything higher is a "beta" build.

vector yy;
yy = vector::Zeros(1);
yy[0]=3.14;
CMatrixDouble cXX;
cXX.Resize(1,1);
cXX[0].Set(0,yy[0]);

//Gives cXX[0][0] = 0.0

[Pär Lansåker]

//OK, I found a workaround

cXX.Set(0,0,yy[0]);

//Still, probably a lot of indicators out there, that will crash when compilated

Unfortunately, the changes made to the ALGLIB library in version 3.19 for MQL5 were quite significant, and therefore backward compatibility is not provided. Users who use the ALGLIB library version 3.5 in their projects are advised to conduct a thorough check of their programs and make the necessary adjustments.

MetaQuotes style, they push the changes and then publish some information about it later, on the Russian site.

You missed it, really ?
