I try to solve a nonlinear optimization problem using fmincon. the initial value x0 is a 467856 by 1 vector. when calling fmincon I have got this error
Error using zeros
Requested 467856x467856 (1630.9GB) array exceeds maximum array size preference.
when I typed 'memory' in the workspace, it showed the following information
Maximum possible array: 11812 MB (1.239e+10 bytes) *
Memory available for all arrays: 11812 MB (1.239e+10 bytes) *
Memory used by MATLAB: 1703 MB (1.785e+09 bytes)
Physical Memory (RAM): 16223 MB (1.701e+10 bytes)
* Limited by System Memory (physical + swap file) available.
Is there any help?
