Ignoring the issue of the extra prompt, what you want can be accomplished
like so:

matlab-history-beginning-search-backward() {
   local search="$LBUFFER"
   zle up-line-or-history
   zle end-of-line
   zle history-incremental-search-backward "$search"
}
zle -N matlab-history-beginning-search-backward
bindkey ^X^P matlab-history-beginning-search-backward
bindkey -M isearch ^X^P history-incremental-search-backward

The tricky bit there is that you use one keybinding to enter incremental
search mode, and then bind the same keys in the special isearch map to
repeat that search.  The other point to note is that you can start an
incremental search with an initial string by passing it as an argument.
