Problem in reshape my grid file (.grd)

I need help, i need to modelling a flow pyroclastic of a volcano (Chile), i have all the codes, but the code that i have didnt work!. Because (i think) i have de dimensions different. Run well in matlab but im using VolcFlow to modelling and when i put the bottom representation, arrise just one axis (figure)

My codes

fid = fopen('out_20_20.grd');

code = fscanf(fid,'%c',4);

ncol = fread(fid,1,'int16');

nrow = fread(fid,1,'int16');

xmin = fread(fid,1,'float64');

xmax = fread(fid,1,'float64');

ymin = fread(fid,1,'float64');

ymax = fread(fid,1,'float64');

zmin = fread(fid,1,'float64');

zmax = fread(fid,1,'float64');

altitude = fread(fid,'float32');

z = (reshape(altitude,ncol,nrow))';

fclose(fid);

[nrow, ncol]=size(z);

I don't know what VolcFlow is. Looks like a third party program someone wrote in MATLAB. Can you ask the publisher?

Hello Enrique, I need to simulate PDC’s as weel with Volcflow, but I have thé the problem. Did you manage to solve the problem, and if so, how? Thank you
